After reading the wealth of very helpful information at:
I started to use ConcreteAlert in v8.5.7 and it works just fine when when I am logged in as a superuser or an administrator but when I am logged in as a normal user it does not work and the browser console returns:
Uncaught ReferenceError: ConcreteAlert is not defined

I have tried it on multiple browsers with the same result - no pop-up modal when not an Administrator. Any thoughts on how to fix this?
