I'm using the User Registration add-on to manage user profile forms. The problem I have is that values (once filled) cannot be deleted. If you delete the value -> save -> the value will still be there.
So, for example, if a user first added his Twitter account, and later wants to remove this value because he quits his Twitter subscription, it's not possible.
Any way to make this possible? Has it maybe something to do with my code?
update_user_meta( $user_id, 'VALUE', $_POST['VALUE'] );
Changing the value works fine though!
