@Palyntir - Unfortunately, I dont know how to add a Flash function to the allowed files - I dont know if it is wise either...
You will have to edit the member.php, register.php, and admin/user.php files, and remove the update queries on a Signature field - It isnt advisable - Just delete the signature field from the template, and then run a Query to set all user signatures to blank...
[sql]UPDATE user SET signature='0'[/sql]
That will set all the signatures to blank (not the signature images though)
If you want to do it on a user by user basis, do the following query for the specific user (
Remember to replace "X" with the userid)
[sql]UPDATE user SET signature='0' WHERE userid=X[/sql]
