Ok well i think i fiddled with something and screwed it up, i can no longer see reputation or warning levels on banned users..
Undo whatever changes you made
If you are also missing post count then you probably removed this:
{$post['user_details']}
Just go to your theme > templates > postbit > postbit_classic or postbit (depending on if you are using vertical or horizontal) and add it below {$post['user_avatar']} .
