Sorry, I had it deactivated since it renders the homepage unusable in Firefox. I’ve reactivate the plug-in.
You can see the JS error in the console in Firefox, along with the page load error (if you compare to Chrome or IE).
The plugin itself is used on this page: https://www.losaltosauxiliary.org/how-we-help
But it is on the home page https://www.losaltosauxiliary.org/ where the error appears.
