Indexhibit Support

I'm wondering if anyone could help - prior to me potentially ruining my site.

I'm thinking of installing Indexhibit for a second time, but within a Sub-Domain folder on my site, this will allow me to have my main site:
www [dot] iamagraphicdesigner [dot] co [dot] uk
and, with a fresh new indexhibit:
www [dot] shop [dot] iamagraphicdesigner [dot] co [dot] uk

My question is, is this possible? To have two indexhibits running separately but accessing the same site theoretically? How do I go about logging in etc, should work?

Or will this just ruin what I already have and cause continued issues?

Any advice/info would be truly appreciated.

You should ask your webhost for directions on how they setup subdomains on their equipment. Not all of them, even Cpanels, are done exactly the same way.
