I have read several other threads that relate to the domain

I have read several other threads that relate to the domain mapping problem with cookies but I haven't found a solution. Here is my current setup.

Wordpress 3.8
Domain Mapping 4.1.1

I have the primary domain: http://ministryconnects.org

I have a "client" domain:

I can view the gravity network multi-site just fine. However, upon login I get the following error:

"ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use Ministry Connects."

I tried logging in using the primary domain and it just redirects to the secondary domain.

I deleted the sunrise.php file, deactivated the plugin, and then reactivated the plugin. This reinstalled the sunrise.php file in the wp-content folder as expected.

I removed the following lines from my wp-config.php file:

define('DOMAIN_CURRENT_SITE', 'ministryconnects.org');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

That didn't work so I re-added them. I also have the following lines in my wp-config.php file:

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('SUNRISE', 'on');

All of these are in the wp-config.php file under the debug definition.

Tried multiple browsers without any success.

I do NOT want to install the multi-domains plugin to get this to work (looked like a solution for a different thread). I won't use the plugin for anything else so I don't want clutter if possible.

I also cannot access the site via the subdomain anymore:

It just sends me to the sign-up page.

I have re-edited the domain to point back to

Also, the plugin page states: "Domain Mapping gives your users the option to map one – or multiple – domains to their own blogs, so myblog.edublogs.org can become myblog.com."

How do users do this? The domain mapping doesn't appear on the user admin page anywhere that I can detect.
