I'm migrating from a web host with CPanel to my own server with Ubuntu 18.04 and Virtualmin. I couldn't get the transfer to work, so I downloaded a complete backup from the CPanel backup tool and then migrated it after downloading.
Nothing works. All the files are there and the domains and subdomains, but it's as if the entire folder structure has been changed. There is now a domains folder that was never there before and all the domains and subdomains point to that folder when all the files are actually in other folders.
So what I get now on each domain I try to preview is an error 403 Forbidden except for the parent domain where I get an "Error" and below that is a white box that says "Invalid SSL certificate : Could not fetch peer certificate.
I'm not quite sure where to begin working on this. Any advice would be greatly appreciated.
Thank you in advance.
