"Hello World" default page — WordPress files were copied to /home/voipsimplicity/htdocs/www/ but CloudPanel's Nginx root was /home/voipsimplicity/htdocs/voipsimplicity.com/. Fixed by rsyncing files to correct directory.
panel.itpropartner.com 404 — Manual Nginx config (panel.conf) was overriding CloudPanel's generated config. Removed manual config. CloudPanel's reverse proxy template had try_files $uri =404 instead of try_files $uri @reverse_proxy — fixed.
CloudPanel MFA blocking login — MFA was enabled on the admin user by default. Disabled via clpctl user:disable:mfa.
Let's Encrypt failure (unproxied DNS) — DNS for panel.itpropartner.com was on SiteGround nameservers, not Cloudflare. Added manually via SiteGround panel. CloudPanel SSL via HTTP-01 challenge required .well-known/acme-challenge directory at reverse proxy site root.
"Error establishing a database connection" — MySQL auth plugin mismatch. Site DB user was using caching_sha2_password but WordPress expects mysql_native_password. Fixed by converting auth plugin.
itpropartner.com not on Cloudflare — Nameservers still at SiteGround. All DNS changes for *.itpropartner.com must be done at SiteGround manually.
