Look in the source code of the page before the you get the 404 page. In it is the form with the action (ie. <form action="thispage.php" etc>). Look to see what that page it that is being called in the action and make sure it is a valid page in that directory.

Just reupload all your vBulletin files and call it a day :D

This can also be caused by badly configured mod_security or Suhosin/Hardened PHP.
