 * Hello,
 * Iget the following error, trying to call up the sliders menu from the wordpress
   dashbord.
    I have a WPMU setup.
 * call_user_func_array() expects parameter 1 to be a valid callback, function ‘
   mslide_dashboard’ not found or invalid function name in /home/www/web383/html/
   wp-includes/plugin.php on line 470
 * Do you have any idea, what I can do about this?
 * Thanks in advance for you help
