I recently finished building my WP theme (child theme of twentyfifteen). My friend started updating content and accidentally added content to a page which don't have a function that gets and displays the content.
From since, everytime we update the template.php file - we cant see any changes on the website, moreover, we see a very old version of the website. We compared the HTML code from the website with the on in the last updated PHP file and it's still uses the old HTML - We totally deleted the .php file of the template - and the page is still displayed!!!
We restarted the server, we deleted all tables in the database using a plugin, and nothing!
I started adding all pages and templates (because all the DB is deleted..), elements suddenly look strange. I changed the templates name from "Homepage Template" to "NEW Homepage Template" and I get the templates in addition to the old strange templates in the template list.
What is happening with my website? How do I stop it?
