Firsts, you have to understand it.

When RealURL is called, it has no idea where it runs. It has only host 
name. So it needs to make a check if it is enabled or not and peform 
path conversions if necessary.

TYPO3 runs extensions for each and every site in the installation, so 
even if you do not use RealURL on other sites, RealURL is still 
activated and executed by TYPO3. It is how TYPO3 works.

So RealURL is called and it tries to find if it should work. In your 
case you do not have domain records or configuration for other domains, 
so RealURL panics and shows you that message.

Solution is simple: confgure all other domains. This is necessary if 
you run several sites in a single installation. Regardless of whether 
you use RealURL or not on other sites, you have to configure it.
