Hello, thanks for trying to help!
Ok, no single or archive.php under my themes.
Here is the code for my index in my themes folder.
https://pastebin.com/XUwAb113
The index files under the wp root seems like the standard install:
<?php
/**
* Front to the WordPress application. This file doesn’t do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/
/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define(‘WP_USE_THEMES’, true);
/** Loads the WordPress Environment and Template */
require(‘./wp-blog-header.php’);
?>
