White screen error!!!! HELP

This morning i was disabling some plugins to try to fix another existing problem, and when i activated them again i had the white screen! Then i started getting a WP super cache error `
Warning: include_once(/home/hartsqua/public_html/wp-content/plugins/wp-super-cache/wp-cache-phase1.php) [function.include-once]: failed to open stream: No such file or directory in /home/hartsqua/public_html/wp-content/advanced-cache.php on line 14

Warning: include_once() [function.include]: Failed opening ‘/home/hartsqua/public_html/wp-content/plugins/wp-super-cache/wp-cache-phase1.php’ for inclusion (include_path=’.:/usr/local/php53/pear’) in /home/hartsqua/public_html/wp-content/advanced-cache.php on line 14

Notice: WP_User->id was called with an argument that is deprecated since version 2.1! Use WP_User->ID instead. in /home/hartsqua/public_html/wp-includes/functions.php on line 3193`

So i deleted the plugins, but i still get the error.. (Screen still blank and still showing error..)
URL is hartsquare.co.uk

Funny thing is.. we have another domain for the site hart square.com.au,,
which is working fine (except the plugins are disabled i think so formatting is wrong)

WP admin not working either
