Hello,
Please check FTP access, we can’t connect.
You are using 8theme – Brand List, but it should be 8theme – Filter Products by Brands https://prnt.sc/1ywfqh5 , then all will work fine. However, this widget doesn’t have the ability to be displayed as a dropdown. Provide correct FTP access, or wait for the next theme update to get the dropdown displaying for the 8theme – Filter Products by Brands widget.
Regards
