The problem I'm having is that users are being shown in a different colour than the one they've selected.

The usergroup cache update is because all of the users are in usergroup 9, so I figured if I set the musername and update the usergroup tags it's a foolproof way to go about it.

OK I've established that my code is fine - and the other plugins are causing the issue.

I have a question though:
Another plugin is calling the fetch_musername function to generate the markup username, using this code:

PHP Code:

if($thread['post_user_displaygid']!=0) 
        { 
            $thread['postusername'] = fetch_musername($thread, 'post_user_displaygid', 'postusername');             
        } 
        else 
        {     
            $thread['postusername'] = fetch_musername($thread, 'post_user_usergid', 'postusername');             
        } 


As you can see, it's calling the fetch_musername hook, on the threadbit_process hook. Now, this doesn't seem to be calling the mark-up username via my hook, almost as if it's being processed before the hook code is being called.

Anyone have any ideas?

After further playing, it seems the $vbulletin->usergroupcache["9"][opentag] & [closetag] aren't being overwritten in the array via my above code.
