Main theme css doesn't load when child theme is added

Hi, I'm using Parallax Frame Pro with a child theme. On my localhost the child theme I created works fine, I have a file named style.css with only this /* Theme Name: Parallax Frame Pro Child Theme URI: https://catchthemes.com/themes/parallax-frame Author: Catch Themes Author URI: https://catchthemes.com/ Description: A hand-crafted WordPress theme for corporate and business websites, Parallax Frame uses Parallax scrolling effects to enhance the user experience and increase your clientele. Simple, clean and fully responsive; the HTML5 and CSS3 codes used in building the theme make it a breeze to work with. Parallax Frame helps you create a website as unique as yourself, making you stand out from the rest of the crowd.

Any idea why? The only difference (besides the one being a localhost and the other a web host) is that WordPress is installed in a sub directory, kind regards, Arjen
