Hey Brendan,
Thanks for reaching out to us!
I took a look at your site and noticed that there were several javascript errors on the page. This could definitely be the culprit for why the maps are no longer working on your site.
In particular, it looks like you’re experiencing the malformed javascript issues that are causing errors now that WordPress has updated the jquery version with WordPress 4.5.
If you’re familiar with using developer tools, you can use them to help you target that code and correct the format there.
Let me know if this helps.
Thanks!
