Logout/Query issue.. help!

[stickskills]

Alright, I've tried contacting vBulletin.. and changing around the cookie issues on my vBulletin forums within the options, but that didn't work, so PLEASE do not tell me that's the issue as I've even had the vB staff go in and tinker around, and to no avail, the problem persists haha.

Here's the SQL query error that I persistently keep getting. I probably get about 5-15 a day, and apparently these are behind the users getting logged out, and having trouble staying logged in quite a few times a day. If anyone can help, I'm sure I can think of a way to repay you.

Database error in vBulletin 3.7.2:

Invalid SQL:

SELECT
post.*, post.username AS postusername, post.ipaddress AS ip, IF(post.visible = 2, 1, 0) AS isdeleted,
user.*, userfield.*


FROM ss_post AS post
LEFT JOIN ss_user AS user ON(user.userid = post.userid)
LEFT JOIN ss_userfield AS userfield ON(userfield.userid = user.userid)

WHERE threadid = 7328

ORDER BY postid;

I did an import using Impex from a Invision Power Board to a vBulletin board awhile back, not sure if that's going to be helpful at all.
