Hello @cupideros,
I am Elvina working with Brainstorm Force, the makers of the Starter Templates plugin.
The issue you’ve mentioned is quite strange. Importing a template fetches the entire website (with pages, content, and media) on the URL you use it on. So, if you tried importing a template on cupiderosgeaphics.com, you will see it there.
You can try restoring the website by referring to the article here.
Furthermore, here’s an article that explains how you can import a template on an existing website.
Also, I realized that you’d like to import templates on a domain like this – cupiderosgraphics.coachcing.com.
This is actually a subdomain that can be created when you enable a Multisite setup on your website.
You will therefore need to enable a WordPress multisite with multiple subdomains that will have URLs like the one you mentioned and then import individual templates on each of these subdomains.
You can refer to this article that will help you set a WordPress multisite that you can work on further.
Please feel free to get in touch if you need any further help.
