I have purchased a WordPress theme called Enfold. When I try to import its demo, I get an error. I have properly configured the server, but it still doesn’t allow me to import the demo. I need a solution for this.

Have you attempted to manually import the demo content ?

Or did you reach out to the theme authors for assistance?
