What is the “100 Unsupported Request Method Type Post” error?

Encountering an error message can throw off your day, especially when you’re looking to post something important on Facebook. The “100 Unsupported Request Method Type Post” error is a technical hiccup that prevents users from sharing their thoughts, pictures, or updates on the platform. This error typically signifies that the method being used to send a request to the server is not supported. In simpler terms, it’s like trying to fit a square peg into a round hole; the action you’re attempting is not compatible with what the server expects. My experience with this error tells me that it usually arises when there’s a problem with Facebook’s backend or an issue with how your device is communicating with Facebook.

Why does this error occur? There could be multiple reasons:

  • Outdated browser or app versions that no longer align with Facebook’s protocol
  • Corrupted browser cache or cookies that misdirect the submission process
  • Temporary server-side issues at Facebook causing communication breakdowns
  • Network glitches that interfere with the posting process
  • Problems originating from third-party plugins or extensions in your browser

Recognizing this error quickly is vital for a swift resolution. Fortunately, since it’s a common glitch, there are tried-and-true steps you can follow to overcome it.

Why does this error occur?

Identifying the Root Cause

When I encounter the “100 Unsupported Request Method Type Post” error on Facebook, I start by identifying the root cause. There are several factors that could be triggering this issue. Sometimes it’s as simple as using an older version of the web browser or the Facebook app that’s not compliant with the latest web standards. Another common cause I’ve observed is related to corrupted browser cache or cookies, which can interfere with the way Facebook communicates with its servers.

Server-Side Complications

Occasionally, the error can stem from server-side problems. If Facebook’s servers are undergoing maintenance or experiencing unexpected issues, it could temporarily disrupt service. This is usually beyond my control and typically requires waiting until Facebook resolves the internal error.

Network Interruptions

I also look at potential network interruptions as possible culprits. Poor internet connection or misconfigured network settings can prevent my requests from being processed correctly. Also, my internet service provider could be blocking or throttling traffic, which can lead to repeated errors when trying to post on Facebook.

Plugin and Extension Conflicts

Another area I check for issues is within third-party plugins or extensions. If I’m using additional software that integrates with my browser, it’s possible it could be causing conflicts. These extensions may intercept or modify requests in a way that Facebook does not support, resulting in the error code in question.

While the reasons behind the “100 Unsupported Request Method Type Post” error can be diverse, I’ve learned that systematic troubleshooting can illuminate the specific cause. It’s important to approach each potential issue with a clear strategy, which is why the next portion of my article will guide you through the most effective troubleshooting steps to get you back to posting on Facebook without a hitch.

Step 1: Check your internet connection

A smooth internet connection is the cornerstone of uninterrupted Facebook access, yet it’s often overlooked. Before diving into more complex troubleshooting steps, it’s essential to ensure that your connection is stable and robust. I’ve learned from experience that a shaky internet can trigger a wide array of errors, including the “100 Unsupported Request Method Type Post” message on Facebook.

To confirm that your network is the culprit, try accessing other websites or stream a video to test the connection’s stability. If pages take longer to load or videos buffer endlessly, these are telltale signs that your connection is on the fritz. For a more quantitative assessment, consider running a speed test through services like Speedtest by Ookla. This can help pinpoint whether the issue lies with your connection speed.

Possible Outcomes From a Speed Test:

  • If you discover your internet speed is below expected levels, troubleshoot by rebooting your router or contacting your ISP for support.
  • If your speed test shows no problems, it’s likely that the issue isn’t related to your internet connection.

Optimally, your connection should be fast enough to handle Facebook’s bandwidth requirements. A slow or unstable connection disrupts Facebook’s ability to process requests, including posting content, and hence may cause the error message to appear.

In the event that your speed test indicates a healthy connection yet you’re still encountering the error, it might be worth checking for any ongoing service outages. Websites like Downdetector offer real-time user reports on the status of Facebook and other major sites. If others are experiencing similar issues, the problem might be on Facebook’s end.

Before moving on to the next troubleshooting step, take a moment to ensure your internet connection is no longer a variable in the equation. With the networking issue squared away, you can proceed with confidence knowing that your path to resolving the “100 Unsupported Request Method Type Post” error is clear.

Step 2: Clear cache and cookies

Once I’ve ensured my internet connection isn’t the culprit behind the “100 Unsupported Request Method Type Post” error, it’s time to focus on my browser or the Facebook app itself. Clearing the cache and cookies is often an overlooked step but it can be the key to solving this pesky issue.

Over time, my browser accumulates a lot of temporary data, which can sometimes cause problems with how websites like Facebook function. To get started, I access the settings or preferences menu of my browser. There’s usually a section dedicated to privacy or history, and that’s where I can clear the browsing data. Make sure to select ‘Cookies and Other Site Data’ as well as ‘Cached Images and Files’ before confirming to clear the data. This step should be performed on all browsers I use to access Facebook.

For mobile users like me who primarily use the Facebook app, the process is slightly different. I need to head over to the settings of my smartphone, find the app management section, select Facebook, and then tap on ‘Clear Cache’. On some devices, I might have to clear the cookies separately. After completing these steps, it’s essential to restart the app to allow the changes to take effect.

In scenarios where I’m not too sure about proceeding with these steps, here’s what I generally do:

  • Check the help center of my browser for detailed instructions on clearing cache and cookies
  • Follow the step-by-step guides provided by the Facebook help section for clearing app data

It’s also a good practice to keep my browser or app updated to the latest version since updates often include bug fixes that can resolve issues like the one I’m facing. After clearing the cache and cookies, I normally check Facebook again to see if the error persists. By keeping my browsing data clean, I not only safeguard my privacy but also enhance my overall user experience on the web.

Step 3: Update your browser

Once you’ve cleared your cache and cookies, it’s important to ensure your browser is up to date. Outdated browsers may have compatibility issues with Facebook, which could contribute to the “100 Unsupported Request Method Type Post” error. Updating your browser is a straightforward process and can often solve a host of problems.

For most browsers, the update process is automatic, but sometimes you might need to initiate the update manually. Here’s how I tackle this process across different platforms:

  • Google Chrome: I open Chrome and click on the three dots in the upper right corner. From there, I go to “Help” and then “About Google Chrome.” Chrome will then check for updates and if there’s one available, I simply click “Relaunch” to install it.
  • Mozilla Firefox: I access the menu button and click “Help,” then “About Firefox.” Firefox will check for updates and apply them automatically. A restart is usually required to complete the installation.
  • Microsoft Edge: I select the three dots at the top right corner, click on “Settings,” then “About Microsoft Edge.” Edge will automatically check for updates and prompt for a restart if necessary.
  • Safari (for Mac users): In the Apple menu at the top of the screen, I select “System Preferences,” then “Software Update.” If there’s a Safari update, it’ll be included here and I can update all software at once.

Remember to restart your browser after any update to ensure the changes take effect. It’s also a good habit to check for updates regularly as part of your routine maintenance.

Keep Your Browser Updated: Staying current with the latest browser version is critical not just for rectifying errors but also for security purposes. New updates often patch vulnerabilities and offer new features that enhance your browsing experience.

If you’re still experiencing the same Facebook error after updating your browser, it might be time to explore additional solutions such as disabling browser extensions or plugins that might be conflicting with Facebook’s operations. Some extensions can interfere with how your browser interacts with websites, and by disabling them, you’re ensuring that they aren’t the root of the problem.

Step 4: Disable browser extensions

When I encounter the “100 Unsupported Request Method Type Post” error on Facebook, one of my go-to strategies is to disable browser extensions. Extensions can interfere with how webpages load and interact with online services. Here’s how to disable them:

For Google Chrome users:

  • Click the three-dot menu in the upper-right corner.
  • Select ‘More tools’ and then ‘Extensions’.
  • Toggle off each extension to disable it.

For Firefox users:

  • Click the three-line menu and select ‘Add-ons’.
  • Choose ‘Extensions’ or ‘Plugins’.
  • Click the ‘Disable’ button for each extension.

Microsoft Edge enthusiasts:

  • Click the three-dot menu and select ‘Extensions’.
  • Find the extension you wish to disable.
  • Toggle the switch to off.

After disabling the extensions, I make a point to restart my browser and revisit Facebook. If the error doesn’t appear, it’s likely that one of the extensions was the culprit. To isolate which one, I turn them back on one by one, checking Facebook with each enablement to identify the problematic extension.

Remember, extensions are convenient, but they can also be the source of various issues. Disabling them temporarily can help you troubleshoot issues like the one with Facebook. Besides, some extensions receive regular updates, so checking for extension updates could solve the issue if a particular add-on was at fault.

Keep in mind that after pinpointing the extension causing the problem, you may want to consider removing it entirely or checking the extension’s settings to see if it needs reconfiguration. Developers often push updates or patches that can resolve conflicts, so it’s always worth checking back for an updated version that’s more compatible with the websites you frequently visit.

Step 5: Try a different browser

Sometimes the simplest solution when encountering an error like the “100 Unsupported Request Method Type Post” on Facebook is to switch browsers. It may seem like a basic step, but browsers differ in how they handle certain codes and requests. Using an alternate browser can sometimes bypass the issue altogether.

When I switch my browser, I usually opt for one of the popular alternatives like Google Chrome, Mozilla Firefox, Safari, or Microsoft Edge. Each of these browsers has its unique architecture and may interact with Facebook’s servers differently. Here’s what I typically do:

  • Open Facebook on a different browser from the one that’s causing the issue.
  • Log in to my account to see if the error persists.

If the error doesn’t show up, it could mean that the original browser’s settings or extensions were the source of the problem. This is a clear indication that the issue isn’t with Facebook itself but with how the browser is configured or how it’s running on my system.

For those of us who stick to one browser for all our internet needs, it may be time to consider using multiple browsers. Not only does this offer redundancy, but it also provides an easy workaround for situations like these. I always make sure my alternative browsers are updated to the latest version. Running outdated browser software can sometimes cause compatibility issues with modern websites.

It’s also a good idea to check for any available software updates for your operating system since these updates can include improvements to the built-in browsers. For instance, Windows updates often come with enhancements for Microsoft Edge.

After testing Facebook on an alternate browser, I tend to monitor if the error shows up again or if it was a one-time glitch. If the error is consistently absent in the new browser, I’ll consider setting it as my default for Facebook or troubleshooting the original browser further.

Step 6: Update the Facebook app

When my efforts so far didn’t fix the “100 Unsupported Request Method Type Post” error on Facebook, I knew it was time to check for app updates. Outdated apps can cause a myriad of issues, including errors like the one I was facing. On my smartphone, I headed to the app store. For iPhone users, this means the Apple App Store, while Android users would look in the Google Play Store.

Here’s the straightforward process I followed:

  • I opened the app store and tapped on the Updates tab.
  • I scrolled down to find Facebook in the list of apps needing updates.
  • If there was an update available, I tapped Update and waited for the process to complete.

It’s important to note that app developers frequently release updates that resolve bugs and enhance security. Staying on top of these updates is vital for ensuring the smooth operation of apps and maintaining a secure online presence. I also made sure that my device’s operating system was up to date, as this can affect how apps run.

Sometimes automatic updates are disabled on devices which can lead to missed critical updates. I always check that my device settings allow for automatic downloads to save myself the hassle of manual updates. By enabling this feature, I ensure that all apps, including Facebook, are regularly updated without my intervention.

After updating the Facebook app, it’s good practice to restart the device to ensure all changes take effect properly. Once my device was back on, I launched Facebook again. Renewing the app this way helped fix issues caused by outdated code and in many instances, could rectify the “100 Unsupported Request Method Type Post” error without further action. I kept an eye on the app performance post-update to catch any recurring errors swiftly. By maintaining current versions of both the Facebook app and my device’s operating system, I give myself the best chance of avoiding common glitches and enjoying a smoother social media experience.

Step 7: Report the issue to Facebook

If you’ve updated your Facebook app and device’s operating system yet the “100 Unsupported Request Method Type Post” error persists, it’s time to directly report the issue to Facebook. Even though the frustration this error may cause, rest assured that reporting problems helps improve the platform. I’ll walk you through how to notify the Facebook support team about the glitch you’re encountering.

First off, you’ll want to access the Help Center from either the app or web interface. Facebook has streamlined the process of reporting issues, so finding the ‘Report a Problem’ section shouldn’t be too strenuous. In the mobile app, look for the menu icon—often represented by three lines—then scroll down until you find ‘Help & Support’. From there, tap ‘Report a Problem’. The web version has a similar pathway: click the dropdown arrow at the top right corner, select ‘Help & Support’, and then ‘Report a Problem’.

When it’s time to describe the problem, be as detailed as possible. Include specifics like:

  • The exact error message received
  • What you were doing when the error occurred
  • The type of device and its operating system
  • The version of the Facebook app you’re using

Remember to include whether the typical troubleshooting steps—such as updating the app, restarting your device, or reinstalling—have already been undertaken. This information is crucial as it guides the support team to understand the nature of the problem and to seek solutions that may not be publicly known or widespread.

Sometimes, you might be asked to send a screenshot. This visual aid can provide the support team with context clues that might not be obvious from a text description alone. Make sure to capture the full screen, as the error message in isolation might not be enough.

Once your report is submitted, patience is key. Facebook receives countless reports daily and yours will be queued for review. While waiting for a response, keep an eye on the platform’s updates. Occasionally, Facebook will release fixes for known issues in subsequent app updates. By staying up-to-date, you may find the error has been resolved before the support team reaches out.


Tackling the “100 Unsupported Request Method Type Post” error on Facebook can be a bit of a hassle but it’s not insurmountable. I’ve walked you through the necessary steps and now it’s over to you. Remember to report the issue if all else fails—it’s your way of contributing to a smoother experience for everyone on the platform. Stay patient and keep an eye out for updates from Facebook.
