Not sure if u have a bug thread (combine this one if u do).. When I post a reply to a thread it does not show up unless I hit reload. This could be my issue..just curious if anyone else sees the same thing
Likely browser caching + this version of vBulletin = what you're seeing. I've noticed that clicking on some links that take me straight to a post it will load the first page of the thread and then jump to the last.
