Would you mind elaborating on what you mean by my SEO config? The whole page/.htaccess?
Yes, those redirects only happen on the pages listed. I found a little more info, however. The redirect only happens when the login URL is
URL/shop/login?back=my-account
But it doesn't happen if I remove the query so it's just URL/shop/login the redirect issue doesn't happen. I also tried creating an account and that did not work. I cannot log in as a customer and the customer account doesn't show up in the admin panel.
