Thread:Project:Support desk/Fatal error: Class 'phpbb user' not found in /home3/vengefu2/public html/forum/common.php on line 102/reply

Have a look at forum/common.php on line 102 and check why class 'phpbb_user' is requested there. The error somehow seems to be caused by the code inside the folder forum/.

However, PhPBB is not an extension for MediaWiki, it is this standalone message board, right? In that case I would ask at a place, where people know more about PhPBB. I am not sure you will get the right hints here...
