SQL database error (prolly from plugin)

[PayBas]

Okay I finally got it:

Database error in vBulletin 3.6.5:

Invalid SQL:

		SELECT  post.pagetext AS preview,
			thread.threadid, thread.title AS threadtitle, thread.forumid, pollid, open, replycount, postusername, postuserid, thread.iconid AS threadiconid,

MySQL Error  : Table '28_vorum.user' doesn't exist

And it's caused by this plugin:

PHP Code:

$hook_query_fields .= ',thread_user.usergroupid, thread_user.membergroupids, thread_user.userid'; 
$hook_query_joins .= 'LEFT JOIN user AS thread_user ON(thread.postuserid = thread_user.userid)'; 


Hook: forumdisplay_query
