Thanks for your response, that sounds really promising. When you say go to More Configure, which page are you referring to? If I can figure that out I think I might be unstuck!

Well, this is good but incredibly frustrating. I was trying to find where the More Configure page was, and without changing literally anything, I decided to just try it again. And it worked. Maybe a cache thing? ¯_(ツ)_/¯ My big concern is that it could just break again since I have no idea what fixed it. Arg.
