1. We do not show any pages other than the forums. If you're seeing "fake pages," that suggests something is up with your computer, such as malware or a virus. (If it were a site-wide problem, we'd have dozens of reports of this issue. Nor can we reproduce it on any of our computers.)
2. We're running TLS v1.3, the latest and last version of TLS. Not sure why your Microsoft Edge browser says otherwise. When I browse the site with Edge, I get no such warning. This also suggests a problem specific to your computer or connection.
Hope this helps...
