We have a custom registration page, located at site-register.aspx. It used to be located at domain.com/register.aspx but there was a bug so we renamed it to site-register.aspx. While the bug was seemingly fixed and we can now rename the page to domain.com/register.aspx, DNN will not use it and reverts to its own default register page. The registration page is set in site settings correctly to point to our custom page. How do we resolve this?
