Hello Kyle,
I have logged in to your site to look for the error. I could not find anywhere where you added this custom JS code. Did you remove it? If you removed it, I am still seeing it. When I checked the plugins section, WP Hummingbird is already disabled. When I open the page in a private browsing mode, I am still seeing the cache generated by the WP Hummingbird. This is weird and could be a caching issue.

Anyway, if you plan on adding the JS script back, please install “Insert Headers and Footers” plugin which you can get in the WordPress plugins section (https://wordpress.org/plugins/insert-headers-and-footers/). You will need to insert the JS code in the footer section provided by the plugin.
