I installed the plugin and after applying all the necessary changes nothing happens if I click on "Check Ninja Firewall". I come to the same starting point again with the button "Enough chitchat, let's go"!
I checked the .htaccess and the new php.ini and the changes are done with the right content. I restartet the apache webserver but nothing happens. If I click on the WordPress sidebar menu on NinjaFirewall I can only see the start page again with the button button "Enough chitchat, let's go"!
Any idea how to make the Firewall working?
