   Not sure what is going wrong, but when I use the following code I am able to add a role to a specific user, however, I am not able to remove a role using the remove_role command.

   Any ideas?

   I can add a role using the following code:
   

   global $user_ID;
   	$user = new WP_User($user_ID);
           $user->add_role('some_role_name');

   But this does not remove the role:
   $user->remove_role('some_role_name');

   I'm checking what roles are associated to the user using the following code:
   

   foreach ($user->roles as $role) {
   		echo "HAS ROLE: $role<br />";
   	}

   Solved this problem later on that same day, so decided to come back in here and post what I found out.

   I'll keep this brief since I have a page on my site that explains everything in greater detail. I'll link to the page at the end of this post.

   Basically, inside the remove_user method contained in the WP_User class, there is an error. The code is checking for the existence of the specified role using

   empty($this->roles[$role])

   The problem is that $this->roles returns an index array with the roles as values. The code above would require a multidimensional array with the role names as the keys, not the values.

   To solve this, I created a plugin which is just a custom class that extends the WP_User Class and overrides the remove_role method. My new method does an in_array check for the existence of the role. All of the existing WP_User functionality remains intact, therefore you can use this new class in it's place.

   You can see the rest of the details and download the plugin here at my site .
