Thanks for your respond.

Not at all, I don't setup any hack or upgrade the vb or ...

[snakes1100]

1. I would globally disable all currently installed hacks, edit includes/config.php and add this to the 2nd line of the file and re-save it to the server.
define('DISABLE_HOOKS', true);

2. Login into phpmyadmin and run a repair of the database

3. Upload/FTP all the default php files for vbulletin to the server again.
