problems adding a new IP to my server

[Ovidiu]

I have a strato server, running debian 6 with ISPCFG 3 - all up to date.
I now have a client that needs SSL so I got him his certificates and need to assign him his own IP. Web server is Apache2

strato comes with 2 IPs by default.

I added the second IP as you can see here: http://screencast.com/t/B4GRNc3Iudz

then changed his site to use this IP here: http://screencast.com/t/BqwjoHDhJOq

and when navigating to his site I get the following error when visiting the site's back end (wordpress):

Not Found

The requested URL /wp-admin/index.php was not found on this server.

Apache/2.2.16 (Debian) Server at www.premaman.co.za Port 80

and the front end looks like this: http://screencast.com/t/mxMfQCBsNE the text is being loaded but all links to images and css files are broken !?

quite weird, have put it back to use the default IP but how can I get this site to use its own IP?
