 * I was attempting to install the asides plug in mini posts 2. When I activated
   it
    this came up Fatal error: Call to undefined function: register_sidebar_widget()
   in /home/findasec/public_html/loveblog/wp-content/plugins/miniposts2.php on line
   533 Now I can’t even get into the admin panel. I deleted the php file etc hoping
   that would help.
 * Can someone help me?
 * Note: I was able to finally get into my admin. I’ll try this again…

 * Your plugin is not listed on this page:
    [http://codex.wordpress.org/Plugins/Plugin_Compatibility/2.1#L_-_O](http://codex.wordpress.org/Plugins/Plugin_Compatibility/2.1#L_-_O)
   Maybe you should check with the author for an updated version compatible with
   WP 2.1. Otherwise it will not work.

 * I was having the same problem and I solved it with this code:
 *     ```
       if(!function_exists('register_sidebar_widget'))
         include ABSPATH."wp-includes/widgets.php";
       ```
