I created one site with forms based authentication and anonymous access. That is working fine. Now i want to replace the master page with the custom master page. I just copied the nightandday.master page and pasted in the same directory of the master pages. Now I changed the master page in the site settings page of the site to my custom master page. With custom master page when I signed out it is showing the sign-in page always. I am unable to show the site with anonymous access with my custom master page. I didn't approve my custom master page and I didn't publish it. Is it may be the problem? If not, How to over come this?
Have you enable the anonymous access at site collection level?
