Aloha!
I am setting up a "mall" where multiple vendors will be in charge of stocking their products. I've just had X-Cart Pro 4.1 installed with a couple mods. I have set up a tester "manufacturer" under 'root' Providers, but I do not see any options for me to customize my store within the main store. Where do I go to upload my template?
Could someone point me in the right direction if this has already been covered somewhere? Thanks!
