Login not working properly

When you click the Facebook login on our home page, I get this error message:

Invalid Argument

The Facebook Connect cross-domain receiver URL (wepromoteyourwine.com/component/jfbconne...%22%3A%220.441%22%7D) must be in the same domain or be in a subdomain of an application's base domain (www.wepromoteyourwine.com). You can configure the base domain in the application's settings.

When I click this screen, it takes me to the following error message:

An error occurred with Wine Promotions. Please try again later.

API Error Code: 100
API Error Description: Invalid parameter
Error Message: next is not owned by the application.

Can anyone tell me what we are doing wrong, or what setting may be causing this. Any help is appreciated as we are going live with the site in a couple days and this is holding us back. This site is not live yet to try the login option.

Thanks

Jeff
