pfsense login from local, remain blank page or black page

This is cause by the package pfblockerNG, when you enable the services and you are using HTTPs with Port 443 to access from local, but you can access from WAN address.

After enable the pfblockerNG, Aliases and rules will created, and you will see the https 443 is redirect to localhost, so you will not get access pfsense GUI from locally.

You can adjust pfsense webConfigurator Protocol or Port to solve this problem.
