The other domain's don't load theme and images

I created a first domain, it accepts all the theme changes.
The other 3 subdomains use the same theme with different logo's.
When I go to the website on shared host it loads the front page.
That's good but the other 3 subdomains don't load theme nor content.

Tried changing theme settings of domain, priority of themes, changing .htaccess with rewritebase
It's like something to do about it can't get in the folders.
The DNS is setup with cname.
When I look to the log messages it's the page not found error for the subdomain.

Already searched the whole internet what could be wrong here.

Can anyone help plz.
