I used the multiple API hack provided by judoman on this page here:
It worked fantastically for me. The issue I have now is that whenever I populated the plugin with store locations and tried to access the store locations from the other parked domains, the store locations do not show up. They only show up on the original domain.
I'm using version 18.104.22.168 of the store-locator plugin
and version 3.2.1 of the WordPress software.
To see it in action:
Our main domain is camelotfs.com (the map works and has icons)
one of our parked domains is camelotloan.com (the map has no icons)
