No, it is listing the urls and methods of logging in failures, which are the answers to your questions. It was only implying the cause could be as a result of the backend changes. I will repost again for you:

- for sure: palemoon / firefox
- other browsers untested b/c they suck.
- http://www.earthempires.com aka portal login.
- Yes to logging out, yes to not logging out. It didnt matter.
- Portal login would only log me into the forums (i was definitely logged out of forums before the attempt to access the game) but the page displayed would tell me cookies werent enabled above the username textbox. I noticed because right after the attempt i was magically signed into my form account when going to the forums.
