I have a similar question. I want multiple subdomains for a single site. It will be an ecommerce site where each subdomain will have the same content except for the subdomain added to address in address bar will need to be seen for every page and I would like to have one image/logo that will be different for each subdomain. Other that that they will be the same.
would it be possible to share the same data base and still have a custom.css file for each subdomain?
I tried to change the wp-config.php but when I click on a new page, the subdomain name disappears from the address bar and I would like it to stay throughout the site.
I hope this make sense.
