Hello @tobiaseigen ,
Thanks and apologies for the late reply. We were not able to completely solve it however after upgrading to the latest Forum and implementing “preformatted text” option in posts, it improved.
It’s sometimes hard to replicate for example
-if I Impersonate a user who is having this problem and try to post it, it’s being posted.
-it doesn’t for for 3 tries then works on the 4th try.
Accordingly we are being forced to offer some unsexy troubleshooting methods such as trying again or posting the text first then editing and adding the code block or URL.
