Forum Database error and slow site
 

Hi Guys!

Got a bit of a pickle whenever anyone on my website tries to post/reply/quick reply. They will get the following error
Code:
Database error in vBulletin 4.1.12:

Invalid SQL:

INSERT INTO postlog
(postid, useragent, ip, dateline)
VALUES
(1407, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0.1', 1705157382, 1348211278);

MySQL Error : Duplicate entry '1407' for key 'PRIMARY'

I'm not much of a database person so not much of this makes sense. If someone could help me out that would be dandy! Hopefully someone doesn't say "Your database is screwed, make a new one". This may be relevant, of late my website has been taking longer and longer to load anything vBulletin related.
