After having issues yesterday with config, I managed to get the GUI working again with the existing config. However today, some webpages wont load, they just go to a white screen. This is happening to all users and only some websites. I have tried IE, Chrome and Firefox and none of them can load website like easyjet.co.uk or
http://www.skyscanner.net/We don't use the firewall to block any webpages.
I have tested to make sure its nothing to do with our DNS and its the same issue on different DNS'.
