After installing the Members plugin into the latest version of WP, upon activation I receive this error:
Warning: Creating default object from empty value in C:\wamp\www\bluesmoke\wp-content\plugins\members\includes\functions.php on line 21
Here's a screenshot of the error: http://i49.tinypic.com/142r2nm.jpg
Note: This was a test installation. I wanted to know if I can safely update my production website. It seems this plugin fails. Any help would be appreciated.
