I'm 100% sure that you have mod_security installed on your server. It is pretty much the only time you run into 406 or 412 errors.

Homepage for mod_security: http://www.modsecurity.org/

Suhosin and the Hardened PHP patch, are addons to PHP (an extension and a patch, respectively) that help with known and unknown security problems.

Like I mentioned in my first post, you may want to get into contact with you host to see if they have some mod_sec rules that are interferring with the passing of the URL/Percent encoded strings to vBulletin.

any other solution can solve this problem ?! please ...

Try putting this

SecFilterEngine Off
SecFilterScanPOST Off

in the .htaccess. That is what I meant by removing the <IfModules> clauses. If that doesn't work, like I mentioned before, your host may have disabled you from modifying mod_security in any way via .htaccess.
