Need help configuring Domain mapping (A Record)


I think I need some assistance to get Domain mapping to work :slight_smile:

First of all my WordPress installation is multisite, it has a dedicated IP, and I've got FTP access.

- I've just imported it into my multisite :
- Now I want to map it.

What I did:
1. I went to the DNS administration of
2. I didn't change the DNS servers settings of
3. I went to the DNS zone of
4. I've just changed the type A cible (I put there the dedicated IP of my multisite installation) of
5. I went to the dashboard of and tried to map domain. I get an error message.

Thanks for your help!
