I was working my way through the Settings and I was on the 3rd tab. When I saved the settings the site redirected to a 404 Page Not Found and I cannot access any part of my site now without receiving that error.
When I navigated to my site (site-pro.net) all I see is a blank page with one word in the left hand corner... error Thanks for making sure that your plugin works. I don't know who rated it 5 stars but when problems exist you better darn well be prepared to answer questions!!
