Hello, thank you for your reply.
I read the article, I enabled “Anyone can register” and in “New User Default Role”, I selected “Customer”. After I went to “Pages”, I looked for the “Registration” page, I clicked on “QUICK EDIT”, the settings were already those indicated in the article, I saved “update”. The page now gives error 404. Maybe it needs to be regenerated? How you do it? What should I do?
