site broke, like there was no css file.
I had changed the directory they requested to 777 permissions, then activated. I cleared the cache.
I deactivated the plugin, refreshed my home pafe - everything fine.
re-activated. clearec cache. refreshed: no css.
deactivaated. cleared cache. Uninstalled.
Site works fine. Used W3 Total cache for minify instead. it's all ok.
BTW I had turned EVERY Minify setting OFF in W3.. (general tab and minify tab) Before Activating this plugin.
