Forbidden:

You don't have permission to access index.php/main on this server.

when attempting to hyperlink certain links. It works for some:

http://www.fox.com

but not for others like?

http://www.cnn.com

but if I take the www out - suddenly it works?

I have been running 9.2 for some time and have not had any issues. This started over the past couple of days and I have made no changed to anything on the software level...

Is this a security blacklist sort of message? If so... what might be done?

Any Ideas?
