if you are using MyBB 1.6.5 OR 1.6.6 then check group permissions for adding signature ..
admin panel --> users & groups --> groups --> edit group --> Users and Permissions --> Can add a signature?
There is no Can add a signature? option.
what is your forum's MyBB version ? may be it is missing and can be added manually with care ..
1.6.6
I upgraded it yesterday.
run file verification tool from tools & maintenance section of admin panel - do you get any files in red color referring changed files ...
^ oh! do you also have ./admin/modules/user/groups.php as one of them - its better to re-upload most of those changed php files ..
