Upon installing and activating WP Super Cache, I get the following error message (paths truncated for privacy reasons):
Warning! WP Super Cache caching broken! The script advanced-cache.php could not load wp-cache-phase1.php. Please edit .../titus2homemaker.com/wp-content/advanced-cache.php and make sure the path to .../titus2homemaker.com/wp-content/plugins/wp-super-cache/wp-cache-phase1.php is correct.
What do I need to do to fix it?
(I did not have this plugin installed prior to the last WP upgrade, so it shouldn't be related to the process of upgrading.)
