ISP: Virgin media.
This is the error I get.
"Error 400
We're sorry, but we could not fulfill your request for /forum/index.php?action=unread on this server.
Your proxy server sent an invalid request. Please contact the proxy server administrator to have this problem fixed."
I got a technical support key and clicked on 'try to fix this yourself', This is what I recived:
"Your request was intercepted by Bad Behavior, security software which protects the Web site you visited from malicious activity, such as hackers, spam and viruses. We apologize for the inconvenience, but your request matched a profile of suspicious activity. This problem is usually quite easy to fix.
Your computer appears to have sent a request through a proxy server which corrupted the request. Uninstall the proxy server and try again. It is not normally enough to simply disable the proxy server. If you are required to use the proxy server, contact the proxy server administrator for assistance."
