Welcome back to the forums, Adam 🙂
Sorry to hear you’re having troubles displaying the Google Maps. Have you tried adjusting the Basic Template Settings found under Events > Settings > Display?

It seems as if you have a template override issue, but it’s hard for me to tell without having more information. I recommend reading through our Themer’s Guide and also Testing for conflicts. I’m confident your answer lies in either one (or both) of these Knowledgebase articles.
Let me know if either helps address the Google Maps issue 🙂
