I’m currently using the twentyfifteen theme to create my application. Now, inside the twentyfifteen themes folder, I have another folder called tuto, inside which is a template that I want to use, named oauth.php. Here’s a couple of screenshots to give an overview of my project’s file structure:
Now, in order to access my oauth.php file, I tried accessing the following link:
http://localhost/wordpress/tuto/oauth.php
However, I get a Object not found! page instead.
I have just started working with WordPress, and would appreciate some help as to how to access templates stored inside a sub folder which is stored inside the main themes folder.
Login into admin and create new page. on right side in select template section you can see your created templates. select your created template and create new page. then you can access your create template just visiting this page.
