I wanted to try this plugin, but after visiting your site php-web-host.com have decided against it for now. There is a problem on your site and it maybe due to this plugin.
I just visited from IP in Australia, and upon clicking links from your footer widget "From the Blogs", was blocked with no page loading. Even a ping would not respond.
After visiting from another country's proxy, I got straight in.
So in summary, something on your site is unjustly blocking some visitors - is it this plugin?
