Custom theme template page is not public

I am new to wordpress. I have made a custom wordpress theme and have added a few page templates to it, that I have used on different pages. Now the issue is that When I deploy the website on the server the the pages are not public (i.e. the user is asked to enter the username and password before he/she can visit the page). Although I have made them public in the edit page section, but they are still not public. When I change the theme and use any of the default WP themes the pages are public. Need some help in this regard.
Thanks.
