Can't find FULLTEXT index matching the column list
 

Hello

I move my DB from one server to a new server.
Now I receive a lot of errors with search script. I find at vbulletin.com and try to solve it* go into AdminCP under vBulletin Options -> Search Type and switch to the vBulletin search and then back to the Fulltext search* but the problem follows.

I try to delete de indexes and make a
ALTER TABLE vb_post ADD FULLTEXT INDEX (title*pagetext)
ALTER TABLE vb_thread ADD FULLTEXT INDEX (title)

But the problem follows

I need help* please.

A sample of error:
Code:
Database error in vBulletin 3.8.1:

Invalid SQL:

SELECT
DISTINCT thread.threadid* thread.forumid* post.userid
FROM vb_thread AS thread

INNER JOIN vb_post AS post ON(thread.threadid = post.threadid )
WHERE MATCH(post.title* post.pagetext) AGAINST ('moon') AND thread.forumid NOT IN (0*79*82*59*30*13) AND post.visible = 1
LIMIT 300;

MySQL Error : Can't find FULLTEXT index matching the column list
Error Number : 1191
And a pic of the indexes of vb_thread db.

Any help?
