D7RC2 new install and first "join"

Adding new member and got following on submit:

Warning: strpos() [function.strpos]: Empty delimiter in /home/workingh/public_html/d7rc/inc/classes/BxDolAlbums.php on line 64

look for a comma on that line..  php=> (item1,item2,item3,)  should be (item1,item2,item3)...do you see the difference and why the error? did u put a comma in the caption? hmm

elseif (strpos($aData['caption'], getNickName($iOwner)) !== false)

Nick is not found...is albums module installed?>
