Thanks a lot for the quick reply, and I’m glad I could find a bug, even if it annoyed me like crazy trying to find the problem without looking through your code. Best of luck with the plugin!
Actually, I already had the Google API key in the options, and I did about an hour of research on your site and others before I made that first post. Just for test purposes, I tried the manual code, which is working fine, so it’s something in your plugin.
