[Plugin: SimpleMap Store Locator] It worked…and then it didn't.

I installed it, added a few locations, and everything seemed to be working great. Then, out of nowhere, it simply stopped.

Everything is still there, but the box in which the map should show is now completely empty- only the background of the page showing through.

Admittedly, I’m far from a programmer, so I have little idea of what to do outside of uninstall/ reinstall, but that didn’t change anything.

Many of the help threads talk about other plug-ins breaking it, but the only other plug-ins I use are Flickrpress and Google Analytics and, even when deactivated, the problem persists.

Ideas?

Many thanks in advance for reading and any help you can offer.
