I run Store Locator on a number of sites successfully. Today, I upgraded the component on a site that had an older, but working version of Store Locator. After the upgrade, the map didn't load at all. (see image)
I've seen problems like this sometimes caused by a JQuery conflict in the past, so I installed JQuery Easy.
With it enabled, a map now appears, but it is only a placeholder. The locations do not load. This is a small site & there are only 2 locations. (see image)
I did get a Google API & tested it in another map module, where it works fine, so I'm pretty certain its not an API issue.
I have also attached a screen shot of error messages when I the page is loaded.
FYI - this seems have been as a result of some strange cache issue. After I posted this, I did nothing. 4 days later the map started working again. Now formatting for the Locations Listings is all weird, but the map works.
I am very disappointed by your non-response to the issue. Very poor support.
