I believe this started the last couple beta downloads, but now after logging in “null” is added to the login which takes you to a 404.
Login via any mechanism (I’ve tried both facebook and regular user login)
Login again and you will get loginmethod/null (previous beta it was no slash just loginmethodnull) - such as:
You are actually logged in and everything works fine once you get away from the Oops not found page…
I’m assuming this is some sort of redirect that isn’t happening correctly, but just thought I would report…
