@NKERIFAC_CLAUD_NBAPNON Could you confirm a few details:
- which plugins are installed?
- are all users having the same problem?
- does this affect just one, multiple or all topics?
- are there any errors in your rails logs?
I would recommend disabling the plugins one at a time while checking if the issue persists, particularly the discourse-ai plugin if you have that installed. If you’re able to identify a problematic plugin, you can try updating it and see if the issue persists after re-enabling it.
Let us know how that goes.
