Dealing with Drupal's Unpredictable User Roles

When Unset() Isn't the Answer

When working with Drupal, you might encounter an error that leaves you scratching your head. The issue arises when trying to modify user roles in a way that Drupal didn't anticipate. In such cases, using the unset() function won't get you out of trouble.

Solution, instead of using unset(), do:

 $form['account']['roles']['#access'] = FALSE; 

This unusual solution will help you circumvent the error and proceed with your user role modifications.
