Error message when accesing main GUI

[alexandruj]

When I try to access the Web GUI, after successfully log in I get the message:

"An HTTP_REFFERER was detected other than what is defined in System => Advanced
You can disable this check if needed in System => Advanced => Admin."

The fact is that I am using pFSense only for WLAN.
So I suppose that I could connect on pFSense only for WLAN, right?
