Hi
This is unacceptable as a response. I purchased the theme from you, the demo site, demo data imports those widgets. The issue is with you as the supplier of a faulty product. You cannot offload your responsibility to a third party.
If these are not available then they should not be in your template and downloaded in the sample data. I’m not about to go chasing a third party when I paid you for a product that it not up to standard.
Please fix or provide a work around.
