DOMAIN HEALTH CHECKERBETA

A Record and "www" Record Don't Match
Code:
A_WWW_NO_MATCH
Level:
Warning
Reason:
If this is not intentional then you need to fix it because your website visitors may be sent to two different web servers.
How to fix:
If you are using CNAME record for your "www" subdomain then make sure you points to your root domain. If you are using A record, make sure it contains the same IP address as your A record.
