Hello,

Can you provide a full URL to that missing page? I would like to check if Composr is properly pointing to the forum zone.

Unfortunately I already gave up and uninstalled the website and reinstalled a fresh one. If the problem happens again, I will post here.

Also, for reference, the forum worked. It was the private messaging / DM system that disappeared after it worked fine.

Okay, noted. Do you remember if you enabled URL schemes, and if so, did you copy the file recommended.htaccess into .htaccess?

@dkpartycomrade For the permissions issue, please create a data_custom/permission_checks.log file, run through the steps to trigger the access denied error again, and observe the log. Then, create a new tracker issue for this problem (include the contents of the log file as well if possible).

So to get this straight, the URL for topicview appears as yoursite/forum/index.php?page=topicview... correct?
Or does it appear as /forum/pg/topicview...
Or /forum/topicview.htm or /forum/topicview/...htm...
