 * Hi,
 * the full error message popping up when I attempt to go into the settings is this:
 * PHP Strict Standards: call_user_func_array() expects parameter 1 to be a valid
   callback, non-static method adminuser::register_custom_menu_page() should not
   be called statically in E:\HostingSpaces\garifalo\garifalohotel.com\wwwroot\wp-
   includes\plugin.php on line 406
 * This is the offending line
    call_user_func_array($the_[‘function’], array_slice(
   $args, 0, (int) $the_[‘accepted_args’]));
 * Anybody?

 * Hi,
 * When you turn on the ‘Debug’ option in UpdraftPlus, it results in any and all
   debugging messages from any part of your WordPress install being enabled on the
   UpdraftPlus page.
 * The above message is not from UpdraftPlus itself, but from some other plugin 
   you’ve got. There’s not enough info there to work out which one (you’d need a
   fuller stack trace).
 * But basically, you can just turn off the ‘Debug’ setting, and you won’t see them
   any more.
 * David

 * Hi David,
 * I deactivated all the plugins, and activated them again, one by one. The culprit
   is the “admin username changer”.
 * thanks for getting back
