localhost in Store URL causes unconfigured or unknown domain warning

[sharon]

I have set up my test system to be run locally and have set the Store URl in setting to be
http:/192.168.1.3/shop/
or
http:/localhost/shop/

The store works fine but I continually get the following entries in the error log

2014-06-28 19:21:37 - App Warning:  AbanteCart core v.1.1.9 Warning: Accessing store with unconfigured or unknown domain ( 192.168.1.3/shop/ ).
Check setting of your store domain URL in System Settings . Loading default store configuration for now. in /var/www/html/shop/core/lib/config.php on line 169

Reading other posts, it seems that this message is generated if the URL does not begin with www - is there a work around to prevent these warnings?

Thanks in advance

Make sure you use only 1 URL to access your store. Add this URL in the setting -> general
