Change domain name in virtualmin redirects to old name

When using the feature on the virtualmin domain: abc.com → server configuration → change domain name. Change the domain to the new name. (123.com)

I am swapping web site names, abc.com was the original live, 123.com was the development.

When renaming abc.com to oldabc.com and 123.com to abc.com, when visting abc.com (the development renamed to live) i get redirected to oldabc.com:10000 (the original sites new name). There doesnt appear to be any way to access the site (abc.com)

I’ve checked in the domain redirects and there is nothing there. The httpd.conf file looks ok too.

Where should i be looking?

Thank you
