Our main domain is ehcanadatravel.com, this is where I require some support.
the ehcanadatravel.ca is a development domain not accessable by the public. It is too bad we can only get support for one, as that makes like difficult if I have problems during development.
Remember that you can use the extension in all personal sites but you will receive support on the domain name registered on our system. My suggestion is to set the domain where you will require support. In general it's the development domain. Or you could use a subdomain.
