Like the heading says. I’ve made templates within Cornerstone. The templates contain webp images however I get an error when attempting to import the templates into another site.
I’ve tried this on different servers with different hosts but I still have the same issue.
Is there something I can do so as to import the webp images when importing templates?
Error in all sites is the same.
