Why "Basic Page Style" is not an option for this website?
I have problems with this internal website at work. I have seen it before at home with www.taringa.net, the problem is that the web page just displays text without the styling sheet settings, and when I go to View > Page Style, I can only see "No Style" then a separator line, and then an option like c3c_base or some custom name. The " Basic Page Style" is not there and I can't view the web pages correctly. If I create a new FF profile, I can then see the page just fine, although the same options are available from such menu.
Didn't upload the Troubleshooting information due to sensitive information safeness.
