I am trying to create a child theme for the Fitness Hub theme. I'm following this guide (https://developer.wordpress.org/themes/advanced-topics/child-themes/), when it comes to part 2. it makes it clear I need to add a 'Template' header in the style.css (of the child theme), however there isn't a template name in the parent theme's style.css. So it's not clear to me what this template name should be. I used 'Template: fitnesshub', but this doesn't work, the child theme does not generate. I get the following error in my themes directory (on the browser):
The parent theme is missing. Please install the "fitnesshub" parent theme.
When I install the parent theme (clicking the link) the same issue occurs.
