MU Subdirectory help

domain: mnopenhouse.net
server: Godaddy deluxe linux
subdirectories: bfl, bfltest, subdirectory2, subdirectory3….

i am trying to set up an e-commerce style website where i will upload products and put them into categories. then those categories will only be visible to certain subdirectories and customers who are logged in with a predetermined password.

so in the end all the products of “category: bfl” will be visible on the “bfl” subdomain but not on the “bfltest” domain

i am trying to run a multisite setup so all the subdirectories will run off the one wordpress install. and i only need to upload the products into the catalog once and can then attach them to categories to show on the different subdomains using a user access manager plugin.

i have gotten the multisite stuff to work, i can create the multisite in the backend, the subdirectory folders show up on the server, the addresses go somewhere, but no theme shows up and can not log in to the site to add a theme.

when i log in to the main site all the styling and everything works.
if i try to log into a subdomain there is no page styling it is just links and text.

example: mnopenhouse.net/subdomain2 or subdomain3 or subdomain4

is there a problem with the setup, or do i need to do something else to make this work?

What are the best steps to take to get this working?

i appreciate any help with this.
Thanks so much
