deafault web page and 404 Not Found


After setting up my WP with all the plugins including Multisite and Multi domain. Every plugin installed is working fine but when I tried to sign up and activate the user/site I got this:
404 Not Found
The server can not find the requested page: (port 80)
Please forward this error screen to's WebMaster.
or this one

Wildcard are added in the DNS Zone Editor - cpanel
(ps. Cannot add wildcard in the cpanel-subdomain that's why I added in the dns zone)

Very strange because I have another site with the same configuration and it work fine.

Any suggestions? thanks!
