Somewhat similar to "I can't log into the main site", yet different because in my case I couldn't log into the Discussion Zone (right where we are now).
I logged on the Main site successfully using my Google credentials (as I always do), but when I accessed the Discussion Zone, my login credentials disappeared from the top navigation bar, just as if I was accessing the site without authenticating.
I tried logging into the Discussion Zone several times, all of which lead me to the crashed UFO error page.
This is how I managed to authenticate into the Discussion Zone:
- I went back to the Area 51 homepage.
- then I clicked on "chat" (at the top navigation bar).
- once on the chat page I clicked on "log in" (at the top navigation bar) and logged in successfully with my Google credentials.
- then I went back to the Discussion Zone, and now I was logged in correctly.
I am reporting this just in case it helps the site maintainers.
For reference, I am using Firefox 57.0.1 (64-bit)
