Coursepress "Already have an account" not working at Signup

Hello,

I have discovered a bug that will not allow users to sign in during the course Sign up process. After clicking the Sign In button on the course page, users that already have logins need to click on the "Already have an account" link. However, when doing so the page simply refreshes and never allows them to sign in.

Known bug? Any tips on how I can fix this issue?
