The errors that come up with Advanced Search have apparently been fixed, but the ones that come up when deleting a PM have not. They are shown below:
Warning: Only variables should be passed by reference in ..../private.php on line 767
Warning: Cannot modify header information - headers already sent by (output started at ..../includes/class_core.php:5755) in ..../private.php on line 926
The message(s) have been deleted. You are now being redirected to your PM list.
