Issue: The root index.php file is showing up instead of my created template-name.php.
What I have done to try and fix: Delete and create a new reviews page with the routename of "reviews". Check my template-page.php to see if I forgot something.
Changed the template to the default template for the reviews page and it gives the same index.php.
Other Important Info:
I have a development environment where the routename works (www.developmentsite.test/reviews), and shows my template-page.
I have also created a page, with a different route, on my production site that uses the review template-page I created and works as well(www.productionsite.com/test-page).
What I need help with: I need (www.productionsite.com/reviews) to show my template-page that I created.
What I think is the issue: There is something wrong with the routename /reviews because even creating a brand new page with that routename, it gives me the index.php root file while using any other routenames, it gives me my default page.php file.
