 * I’m getting this error message in a few places in the dashboard:
 * Warning: call_user_func_array() [function.call-user-func-array]: First argument
   is expected to be a valid callback, ‘Tweetbacks_Admin::add_config_page’ was given
   in /home/content/p/u/r/purplehays/html/Blog/wp-includes/plugin.php on line 311
 * Any suggestions for repair?
 * Thanks! – Bob

 * And I have a fix….
 * The code to try to only create the admin class once doesn’t work right, so comment
   out the line:
 * `if ( is_admin() && ! class_exists( 'Tweetbacks_Admin' ) ) {`
 * and also the last line below (the previous endif included to help guide you to
   the right line:
 *     ```
       } // end class Tweetbacks_Admin
   
       } //endif
       ```
   
 * and I believe the error will go away. Don’t know if we’ll see a slow memory leak
   or not, just starting to test the longer term affects now.
 * Thanks! – Bob
