Hi, Just an FYI: On April 29, Bluehost automatically overwrote all cache plugin files with the updated files on ALL SITES; eg, WP Super Cache and W3 Total Cache. As a result, the WP Super Cache settings get hosed and the site breaks. I use mod_rewrite to cache and the overwriting of files makes it so menu links are 404. To fix it, you have to reset all super cache settings and re-apply the htaccess rules.
BTW: Love Super Cache.
