I purchased your plugin for a client http://www.shapleys.com and everything was working fine. I bulk uploaded over 2,000 locations. Recently the locator stopped working and I have tried to find an answer on your site and fix it on my own. Figured I had just done something wrong. I came across an item under known conflicts for Theme Forest - could this be my problem? I am using the Karma Theme by them. I believe it also indicated you had a fix for this issue.
PROBLEM the map appears with my location and pins visible. When you enter a location to find it locates the zip and put a yellow icon but no pins appear in a 200 mile radius. If the location is out of the zoom level of the map you must move to the location to see the yellow label - again no pins appear.
