 * Hello,
 * Since 3.0.10, I have the message:
 * Warning: call_user_func_array() [function.call-user-func-array]: First argument
   is expected to be a valid callback, ‘bwps_admin_construct::backup_scheduler’ 
   was given in /xxx/wp-includes/plugin.php on line 405
 * at the top of all admin pages.
 * Thanks.

 * I have the same issue when I installed the plugin.
 * Old pages (before plugin installed) were not accessible anymore. Every action(
   updating menu / adding pages-media-post) triggers the error as mentioned above
   and a 404-error when accessing them.
 * Even deactivating the plugin keeps causing trouble. Going to reinstall everything–
   is going to be quicker & easier then waiting for a (possible) fix.
 * Plugin looked promising but causing too much trouble, as I see other WP-site 
   owners experiencing the same problem. Seems the last version is a Beta-version.

 * I’ve got the same problem too after updating to 3.0.10, deactivate or deleting
   do nothing.
