Tried multiple times to get the WP version installed, but was never able to get the firewall admin page up. The install process just kept on creating new htaccess and ini files. However, the paid version works fine and the install was very well explained. They say it is specially created for shared hosting, so since I am using VPS hosting, makes me wonder if this is the right solution for me.
Anyhow, just a little annoyed that I could not get the WP version up and running and had to buy the paid version just to test it. Still searching for a WP firewall. Maybe the creator could chime inn and let us know how this firewall works in a VPS/Dedicated server environment.
