Hi @evansims
Thanks for the suggestions.
I have just tried clearing the session on my server, and opening a chrome and firefox window in incognito. It appears that this does not change the behavior.
When I attempt to sign up, it successfully signs me up, but redirects me to the / page of my app, where I see the login button again. I notice that it does not create my user in the DB as the quickstart guide mentions that it should.
Once I click the login button again after signing up with a fresh user, then I get the same error message: Can't initialize a new session while there is one active session already.
Do you have any other ideas here? Thanks.
