I have set up e-commerce and User accounts on this project - but whenever anybody tries to sign up / create an account to make a purchase, I get the same generic error:
“There was an error signing you up. Please try again, or contact us if you continue to have problems.”
Also having this issue. Site has a plan and is published but can’t sign up a user to test.
EDIT SOLVED: Try a longer password for the test user. It wouldn’t accept Test01 but accepts Testing01 as a password, so I’m guessing it has an 8 char minimum.
