A bit disappointing that is your solution. The website has already been built with LearnPress. I’ve chatted with their developers and they said this is a theme issue.
Have you come up with a solution? This is a huge issue at the moment as the users are signing up and not enrolled in the courses – which is causing a ton of confusion.
Are you sure it is functioning correctly? If you are logged out, and make an account, the URL is appended with redirect_to however it takes you to the profile page, NOT where you left off / enrolling.
