After deleting indexes for some categories it worked to delete. It was a very helpful thing, thank you again.

But for some I get a database error, I don't know why. This is why now I try to prune.

In Prune mode it seems it progresses. It shows a page with points that advance, like something good happen.

When I try to Prune some forums I get the following database error. Any ideas why?

Database error in vBulletin 3.7.4:

Invalid SQL:

SELECT *
FROM thread AS thread
LEFT JOIN forum AS forum ON (forum.forumid = thread.forumid)
WHERE 1=1 AND thread.lastpost <= 1283899970;
