guys pls help moved my site to a website builder this weekend. www.mydomain loads perfectly. but type teh domain without www and it shows a parked page.

This site can't be reached
Check if there is a typo in my-shop-site.example.
If spelling is correct, try running Windows Network Diagnostics.
DNS_PROBE_FINISHED_NXDOMAIN
the host's docs say to add a CNAME for the root domain, but a budget registrar refuses and says a CNAME cannot coexist with other records... i don't want to lose visitors who type the short version... what's the correct way to handle this?? i'd love to understand teh why, not just copy another record from a forum.
