It is a reptetive question and i saw forum for answers but all had a different source.
I have vb 3.8.2 and it is the first version i installed. every time a new user register and login to website get this message :
Your submission could not be processed because a security token was missing.

If this occurred unexpectedly, please inform the administrator and describe the action you performed before you received this error

Create a new style with no parent:
Styles & Templates > Style Manager > Add New Style
Parent Style: No Parent Style
Title: Default vBulletin
Allow User Selection: Yes
SaveSet this new default as the default and then try to register using this new style - do you still have the same problem?

If it is still happening - Try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);Don't forget that for vbseo, disabling the modification means to also get rid of anything extra you added to your htaccess file.
