Problem with attachment files

The problem is for old attachments files, not for new.
New files are fine.

I found the problem, but I need a fastest solution for repair it.

In SQL Table, the table "wp_wpforo_attachments"

I need to change the name of "fileurl" 

The last name was
fileurl = //domaine1/wp-content/uploads/wpforo/attachments/nomdufichier

And I need to be :
fileurl = //domaine2/wp-content/uploads/wpforo/attachments/nomdufichier

Do you know a sql request for change name of 5000 files faster ? and not 1 by 1 ?

Thank you !

Just backup this table and execute this SQL in the database > SQL tab. Make sure wp_ prefix matchs to your table prefix and change the "olddomain.com" and "newdomain.com" to your original domains:

UPDATE `wp_wpforo_attachments` SET `fileurl` = REPLACE( `fileurl`, '//olddomain.com/', '//newdomain.com/' );

Thank you very much, I will try it soon.
