I'm writing this as of Sept. 20, 2012 and just built a beautiful site and now have to deal with the mess and headache this piece of crap plug-in has left me to clean up. Major freeking headache.
((((( Puh-leeeze do not install this plug-in on your site unless you want to attempt to manually remove it while scratching your head and wasting another couple of hours of your previous time. Even better yet, the uninstall instructions force you to go into your .htaccess file and edit it with their vague instructions on "delete this and that".
This is scary at best since I have no back-ups of this file to compare against since it is an invisible file (and I do have site and database back-ups but they don't include the *original* .htaccess file).
When I de-bug this plug-in from within the WordPress Admin area, I get the message - "not caching Admin requests". SO this plugin is not working and is ignoring any changes I make using the WordPress Admin Tool (So if I make a change, say, using a widget, then the contents of the widget are not updated). This is because this plug-in essentially ignores the whole WordPress Admin Tool / a.k.a. the whole Content Management System. Really folks?
Even worse, it blocks me from clearing my cache manually on my browser (Firefox on a Mac) so I attempt to make a minor stylesheet change and although it appears the file uploaded, it is not udpating. More mess.
THIS PLUGIN SHOULD BE TAKEN DOWN OFF THE SITE! Why leave this up to mislead and frustrate others?
