 * When I updated to Simple Fields 1.33 I got an error message from PHP
    `Undefined
   function simple_fields_register_field_group();`
 * Is simple_fields_register_field_group() no longer a part of simple fields or 
   is it just a bug?
 * Thanks in advice!

 * I think something just went wrong when I updated the plugin through the WordPress
   admin panel..
 * Now I just deleted the plugin and reinstalled it and deactivated all the functions
   that were using simple_fields_register_field_group(); so I could reactivate the
   new version and then it worked.
 * Why do I have to do it this way?
