Maybe also you want to redownload the latest code and reapply any plugins. We have has this same discussion before on the beta.
I actually show your issue is you have not properly upgrading as your missing your photopost.css template in vbulletin which means you are not running all the latest plugins.
Both the 8.01 and 8.02 releases had changes to the plugins and required you to redo the
vb plugins.
Your gallery is looking for a photopost css file from
vb and it just simply is not there. Your gallery doesn't look totally whacked because you still have old declarations for the gallery in your
vb additional.css template.
