Hi, @ibrahim791.
Thank you for getting in touch and we’re sorry that you’re facing issues with import.
Looks like that import file or some media files that need to be imported are inaccessible. The import file accessibility needs to be taken care of by the theme author.
Can you share which theme do you use, please? We can try to replicate the issue and confirm if it’s an issue on the theme author’s side.
Use the One Click Demo Import support forum to create a topic regarding this issue. We’d be happy to help.
Kind regards.
