How can I change the max length of the drupal 7 signature field to more than 255 characters? I've already changed the sql data type from 255 to varchar(900), yet drupal still shows the error, as soon as a user wants to update his signature to more than 255 characters.
I know this isn't the case but you can look around the module(code) and do this but you are on your own ,, because its dangerous
This module allows you to change (uneditable) settings for fields.
READ WITH CAUTION: Please don't use this module unless you know what the hell is this module does which I'm NOT sure about 100% ,, so I'd recommend using it in stage/dev/local environment until you are sure about it
