Domain mapping, A records and site goes to old WP innstall.


The website that I have installed the domain mapping plugin on is which is a wordpress multisite on a dedicated IP.

I have installed and set up the domain mapping plugin. I created a test site in my network called

I have an old site with domain:

I tried to map to the testsite in my network.

I added my IP address to the domain mapping plugin and changed the "A" record to my networks IP address.

The problem is that instead of showing the new testsite in my network, it's showing the same old WP- install that I no longer want associated with There is no visible change.

I have also removed the 4 lines from wp-config as adviced if things arent working properly:

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

What can I have done wrong?
Or did I miss a step?

Kind regards
