Your Photopost worked before you started moving stuff etc what would you like me say other than put it back the way it was.
I would suggest you download complete unedited files and reupload them. The sql error your encountering has nothing to do with Photopost in any way shape or form. Check your config-inc.php to make sure you have the correct mysql information for vbulletin under the user database portion. Make sure in your photopost settings table via phpmyadmin make sure your setting 83 has the proper vbulletin database table prefix in there. Also try disabling any vbulletin hacks you have installed.
It is a process of elimation because our files are not calling the bbcode table.
