A child theme is an extension of the parent. It does not replace the parent. It depends on it. The only purpose of the child theme is to host modifications to the parent theme that are “protected” from parent theme updates.
And the principle is pretty simple:
Whenever WP needs a theme file, it first looks in the child theme for it. If it’s not there, it loads it from the parent theme. So whenever you want to modify a parent theme file, you have to copy it in your child theme, keeping the exact same folder structure and apply your mods to it.
There are two files that do not apply to this rule: functions.php and style.css, both placed in the root of the child theme. These two files should only hold php and css additions, not the parent files code. As you add php or css custom code, for different functionality, you put it in these two files.
This is simplistic, you should read the complete documentation on how to make a child theme on Customizr website.
And yes, my advice still stands. You have deleted important parts of your parent theme, which are required for your website to function properly.
