Tell us what you are trying to do?
I am trying to apply a template to a post type, it worked before but I've just updated the theme (xtheme) and now it seems like Toolset it's not able to take xtheme over.
Is there any documentation that you are following? No
Is there a similar example that we can see? hidden link it's happening here, the template name is web-projects-v2
If you'll check the custom CSS code added in both these templates, you'll see that the one in the "Web Projects" template uses color codes directly, while in the "Web Projects (v2)" template it is using CSS variables ( ref: hidden link) which haven't been defined.
Example screenshot of the differences: hidden link
You'll note that if the custom CSS code from the "Web Projects" template is included in the "Web Projects (v2)" template, it applies correctly.
