منتدى استراحات زايد - Forum Newly posted thread sometimes makes a DB error

Sometimes after posting a new thread, I have vbulletin spit out a response similar to this.

It doesn't happen all the time but it is annoying when it does, any help with solving this problem please?
PHP Code:
Database error in vBulletin 4.2.0:

Invalid SQL:

SELECT thread.threadid, thread.forumid, thread.title, thread.prefixid, thread.taglist, postusername, postuserid,

FROM thread AS thread
INNER JOIN forum AS forum ON (forum.forumid = thread.forumid)
LEFT JOIN post AS post ON (post.postid = thread.firstpostid)

WHERE thread.threadid IN (190498,187845,181478,182586,165329,19769,165825,188494,) AND thread.visible = 1
