blank page means php fatal error (Which most likely means something is wrong with the 1.18beta).

Could you put error_reporting( E_ALL ); ini_set( 'display_errors', 1 ); At the very top of your LocalSettings.php file? This will make errors be displayed (instead of just having an empty blank page). Let me know what the error is after adding that, and we can probably debug it from there.

Thanks, Bawolff
