Won’t let me create a login – Mage | Market for Magic (MTG) Review

Whenever I try to create a login it has a pop up saying that “some information is wrong.” I’ve checked all the information I put in but everything is correct. I don’t know what to do and I can’t use the apps features without logging in. Also when I tried using the gmail log in it said that I had invalid credentials. I’d love for this to be fixed.
