Hi @Shender,
It seems that you haven’t configured your domain correctly.
To start with: as I remember it is not allowed to add CNAME records for a “root domain” (in your case - fmradio.site).
I would advise to create a CNAME record app.fmradio.site, point it to hosting.adalo.com and then set up everything in Adalo.
P.S. You can see the long thread here Any GoDaddy domain owners? Adding DNS CNAME doesn't work, there is a workaround if you use CloudFlare.
Best,
Victor
