I have the same problem:
Warning! WP Super Cache caching broken! The script advanced-cache.php could not load wp-cache-phase1.php.
Please edit /home/content/76/10946776/html/wp-content/advanced-cache.php and make sure the path to /home/content/76/10946776/html/wp-content/plugins/wp-super-cache/wp-cache-phase1.php is correct.
I have no idea what the edit instructions above are referring to... any quick fixes???
Thank You!
Shirley
