When you create a post on vB there’s a checkbox to tick & choose whether to attach signature or not to the post. When a user has no signature, that checkbox is unchecked, which means that when they finally create a signature they will attach it only to the new posts. If they want to attach it to the old posts, they will have to go edit every post & tick that checkbox. I don’t know of another way unfortunately, maybe some SQL query could do it.

My modification will just add a signature to any post that hasn’t one, it’s not the cause of your problem.

but i had a problem that when the user make a signature for himself , it appears only in the new posts !

and his own old post still have the default signature that i created !

is there anyway to overcome this problem ??

any help will be very appreciated
