Can I still use mobile joomla without sub-domains?

Hello, Before I used to make use of mobile Joomla without using any sub-domain. After installing version 1.0.1 I started getting errors. I noticed that in the Advanced Settings tab there is a window subdomains. If I empty these I get error on the desktop website!! So I guess it is no longer to use mobile joomla without sub domains right?

You should empty subdomain fields, but not URL field.

Thank you. That worked fine.
