URL Redirect on GoDaddy platform [closed]

In the DNS we have an A record for www pointing to the ip address.

You will also need an A record for the domain apex pointing to the same IP address. Or, preferably, an A record for the domain apex pointing to the IP address and a CNAME record for the www subdomain pointing to the domain apex.

You can then implement a standard non-www to www 301 redirect in the .htaccess file associated with the WordPress installation. For example, at the top of the relevant .htaccess file:

# Redirect non-www to www
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

The above will redirect any request where the requested Host does not start www. and prefix the www. subdomain via a 301 (permanent) redirect.

Test first with a 302 (temporary) redirect and make sure you have cleared your browser cache before testing, since the earlier (erroneous) 301s (by Godaddy) are likely cached.

NB: I’ve used https:// in the above, but I notice you are using plain http thoughout your question?
