Multisite front-end going in loops


My client is running a WordPress multisite network.

The first .dk domain works fine on the front-end and back-end. However, the second .com domain only work in the back-end but not on the front-end.

When trying to access the front-end it gives me a redirects-loop error. Please see

I have checked the wp-config.php file and .htaccess file and everything looks right.
