I need help, total noob here
 

Hey all. I think I'm out of my league a bit here, but my forum is having issues. No one can post and we are getting this error:

Database error in vBulletin 3.6.5:

Invalid SQL:

SELECT posthash.threadid
FROM vb_posthash AS posthash
WHERE posthash.userid = 2 AND
posthash.dupehash = 'b57dbed1714a8f248614a6d80f53deda' AND
posthash.dateline > 1263472509;

I had a friend in a different country set it up for me, and he isn't always readily available.

If someone could help out it would be great.
