Sorry for the confusion
When people access our site
www.mydomain.com (not /xcart/home.php) they only see brief info eg. company info, and then they are required to log in in order to access the shop section, which is
www.mydomain.com/xcart.home.php and other functions outside xcart. We trying to integrate xcart with our simple html web pages.
Hope this is better worded.
Thank you
