Bug when changing user password

[youjoomla]

I get this when I try to change user password in admin and frontend

WARNING: join() [function.join]: Invalid arguments passed in line 134 of file vbulletin3.inc.php

also user rank is not shown until he makes a new post

There is no such file as vbulletin3.inc.php in vBulletin. This would be caused by some addon that you have. You need to contact the author of the addon for support with their code.
