Fatal Error BEFORE dashboard

Hi there,

I tried to log into our site this morning and got this error: Fatal error: Call to undefined method stdClass::in_admin() in /nfs/c07/h01/mnt/98301/domains/ontarioculinary.com/html/wp2011/wp-includes/load.php on line 587

I’ve combed the threads for a solution, but they all involve logging into the site and preforming fixes. I can’t even get to the log in screen. Both front and back end of our site are down.

Does anyone have any suggestions?
