Installation


after installing on an existing site then trying to setup my first slave site I get this error
troodeals.com
what am I doing wrong?

This is a joomla standard code that is called on IIS platform and that try to get the information present in the URL.

Can you confirm that you are working on IIS or Windows platform.

Perhaps you should report the warning directly to Joomla.org to mention them that sometimes the QUERY_STRING is not defined.
