Your host is most likely using NameVirtualHost entries which means more websites use the same IP on a server.
If there is a typo in the VirtualHost directive of apache or if the
VirtualHost directive of your site is non existent Apache will send
the user automatically to the first VirtualHost directive that either
uses that IP address and if that doesn´t exist it will go to the
very first VirtualHost that is in the config.
This is probably what is happening.
