A Facebook bug had caused major issue for users like disappearing posts and blocking links. The bug affected posts with links to content from outside of Facebook.

Users making an attempt to post new links faced a security warning. Users who clicked on existing links conjointly faced similar warnings, saying the link has been blocked for security purpose. many posts containing links conjointly disappeared.

The issue was initial reported in Facebook’s developer’s forums.

A Facebook representative told TheVerge, “An error in our system that helps block bad links on Facebook incorrectly marked some URLs as malicious or inappropriate. As a result, some existing posts were hidden, whereas different posts were blocked completely. We’ve resolved the problem and therefore the remaining affected URLs are being unblocked. we apologize for the inconvenience this has caused.”

“There may be a security bug with Facebook that’s removing posts (seemingly from the last 24 hours and page posts today) similarly as a second issue with links not working properly,” the company said in a statement.

Facebook has reportedly resolved the problem.
