When I click on "Home" in bread-crumbs or the "Home" link way up next to the Log-In in it opens a 403.html error page instead of the store's main page:

http://www.musecards.com/store/index...ain_page=index

I know it's because the URL ref is incorrect, but i don't know where to correct that in the code.

Is that in one of the PHP pages, & if so, which one?

Thanks in advance,

Alice
