wpme-google-maps

I have been tried in both localhost and live site. The map shows only few days at the beginning and then has gone. I tried many times in configuring API key, Initial Zoom Level, Content for Info Window as there are no hints for these errors. I even checked all the address in Google and tested with the map one by one with the plugin. However, the maps disappear again few days later. Time wasting and exhausting!!!

the plugin works correctly and service is courteous and quick. Thank You
