Meanwhile I tried this: http://www.vbulletin.com/forum/forum...for-all-forums but that query haven't worke.

Try:

UPDATE forum SET options = options + 2097152 WHERE NOT(options & 2097152);

But make a backup of the database first before running the query.

Just so you know, the above query is 'not' the same as the one you linked to:
http://www.vbulletin.com/forum/forum...for-all-forums

It's slightly different.
