Facing FetLife Error Code 500? A specific payload can block all user posts, causing access issues. Learn how to fix and prevent this vulnerability effectively.
FetLife is a popular social networking platform designed for individuals interested in alternative lifestyles. However, like any website, users sometimes encounter technical issues—one of the most frustrating being the FetLife Error Code 500 (500 Internal Server Error). This issue can prevent users from accessing their posts, interacting with others, or even logging in.
What is FetLife Error Code 500?
A 500 Internal Server Error is a common HTTP status code indicating a problem on the website’s server. This error means that the server encountered an unexpected issue and could not fulfill the user’s request.
Unlike client-side errors like 404 (Page Not Found), a 500 error is caused by an issue on FetLife’s end. However, some factors on the user’s side may also contribute to the error.
How Does This Error Affect Users?
- Inability to access posts under
/users/OUR_USER_ID/posts - Complete inaccessibility of some or all pages
- Slow or broken loading of FetLife features
- Errors when posting new content or commenting
- Occasional login failures
Causes of FetLife Error Code 500
1. Server-Side Issues
Since the 500 Internal Server Error originates from the FetLife server, the most common reasons include:
- Temporary server downtime
- Overloaded servers due to high traffic
- Database errors preventing proper retrieval of user posts
- Incorrect server configurations or software updates causing conflicts
2. Markdown Processing Vulnerability
A recently discovered vulnerability in FetLife’s markdown processing system can trigger a 500 error. If a user submits a post containing a specific payload, all posts for that user may become inaccessible to others.
The problematic payload example:
[PoC](())
is an invalid character, causing the markdown processor to break.)is decoded as a), which can lead to further issues.- When a post containing this payload is published, all posts from that user become blocked, and a 500 error appears for anyone trying to view them.

Your browser’s cached files and cookies may sometimes interfere with how FetLife loads, leading to error messages and loading failures.
4. Browser or Device Compatibility Issues
If you are using an outdated browser or an unsupported device, FetLife may struggle to function correctly, occasionally leading to a 500 error.
