I am stuck in a peculiar situation. I have a store on BigCommerece configured with a domain from GoDaddy (mystore.com). I recently created a custom wordpress blog and hosted it on 1and1 hosting (s418783372.onlinehome.us), since bigcommerece can't host Wordpress.

Now I want to use it from a sub-domain of my main-bigcommerece store (models.mystore.com), but it doesn't seem to be working since BigCommerce is the Doman Manager, but GoDaddy is the Domain-Registrar and 1and1 is the host so it doesn't control the domain.

I have tried setting up a CNAME record on BigCommerece and when it didn't work asked BigCommerece about it, but they said they can't do anything about it since they aren't the domain registrar and gave me a message saying:

The responsiblity to show the name in the browser on the site is up to the server or site admin. The Cname can only get the browser there
