My current hierarchy is as follows:

* Custom Post Type: Projects (projects.php)
* single-projects.php

I've checked out this link: <https://wordpress.stackexchange.com/questions/202859/custom-post-type-pages-are-not-found>, but flush\_rewrite\_rules( false ); doesn't seem to work. I've also tried manually saving on the permalinks page, but it was either the projects.php being able to appear, or single-projects.php appearing, but not both.

Code in functions.php from <https://getflywheel.com/layout/how-to-create-a-portfolio-for-your-wordpress-site/>:
