I recently installed a new modem/router and tried both Firefox and chrome to access the modem setup via a webpage but after entering user name and password could only get a blank page in Chrome and in Firefox, all it had was Content-Length: 403 . I don't normally use IE but tried it and it worked. As I don't normally use IE, I checked in ESS to see if it was ticked in Active Mode. It wasn't so I ticked it. When I later tried to access the modem webpage in IE, all I got was Content-Length: 403. I then tested all the web browsers and with Active Mode unticked, I could access the modem webpage but with Active Mode ticked, there is only the Content-Length: 403 message. Does anyone know why this would happen. I have never been blocked from a web page before so don't know if this could affect other web pages and the internet was working ok even though I couldn't access the modem. I am leaving Active Mode ticked but just untick it if I need to access the modem. I did initially search the web for info on Content-Length: 403 and found it is a common problem so I am not sure if others are using ESS or it is an issue with some firewalls.
