This means that WordPress will create a new folder at wp-content/uploads/sites/02. All of the uploads for that site will be stored in that folder, in the same year and month based structure as is used in a standard site.


Hosting Provider

Your web hosting service provider should be capable enough to handle multiple domains in a single web hosting plan.
