I am definitely one of those who is not using a Security Token. Thus, from all 56 ".php" files in the "vB 3.7/upload" directory, I have changed all those
define('CSRF_PROTECTION', true);
to ->
define('CSRF_PROTECTION', false);

All my mods and plug-ings are working fine again and the board is running smoothly.

It will be good if the vBulletin Development team could give an option in the Admin CP (->vBulletin Options) to switch on/off this "CSRF_PROTECTION" depending on whether a customer uses a Security Token or not. This, as few people are actually using a "security token".
