Database error when posting

[CaptainAwesome]

I was trying to do a test post on the forum today to see if something took and when i hit the "submit new thread" button i get the following error:

Database error in vBulletin 4.2.2:

Invalid SQL:

INSERT INTO postlog
(postid, useragent, ip, dateline)

There is only 2 things i have done today to the site. I tried to import a database to my host so i could transfer the forum over but it would not import.

The other thing i did was reinstall this because my affiliate ID had changed. I didn't delete anything prior, i just re-uploaded it with the correct info:

Thinking it might be something i did today, I tried to roll back the site to a few days ago and its still happening.

When i go back to the site, the posts that generate this error are displayed.

Any suggestions? I would have thought rolling back the site and database to a few days ago would resolve this but no such luck. "Duplicate entry '7' for key 'PRIMARY' " doesn't mean much to me but i'm sure the pros here know exactly what it is.

Thanks

Is it always exactly the same message, that is "Duplicate entry '7' for key 'PRIMARY'"? If the number increases by 1 each time the error happens then I'd say that the problem is that the postlog table somehow has more entries than the post table does. Did you maybe try to "reset" your forum at some point by truncating the post table (or maybe your attempt to import a database did it)?

In any case, you could probably just truncate the postlog table, since if you're only on post #7 I'm guessing it's a test forum and you don't care about the log info.

Yes, it was increasing by 1.

I didn't try to import a database into vbulletin, i tried to import one to my host so i could use impex to import my forum over.

The "Fix Unique Indexes" in the maintenance part seems to have solved the issue.

Thanks for the help
