[Solved] Can't sign into old account using Facebook. Tells me I need to use an email but don't get the option to enter one

As the title says. When I click the hyperlink under where the site asks you to enter an email to create a new account and click sign into facebook, I get brought back to the main page with an error message telling me I need to use an email to sign in.

EDIT: Received a code in my inbox and was able to sign in. Apologies!
