Mapping a new domain is not working (DNS propagation OK though)


The subsite is mapped with a domain today. It's been mapped to the same domain for a year now and it's work as expected.

My problem is that the client want to map her subdomain with another domain today (replacing the previous mapped domain). DNS propagation looks OK and when you type the new domain you are redirected to as expected.

But when you want to map the subdomain nothing happens (no error message, it just keeps going and going and... nothing happens).
When you remap the subdomain with the previous domain everything is working in about 1 or 2 seconds.

Hope I'm clear enough... :wink:
Any idea?
