EPATaskbox is not defined


We are setting an on-premise installation of OS,at some point (perhaps after installing lifetime) the EPA Taskbox stopped showing up on all the applications.

Instead of showing the little square at the bottom right of the screen, I now get a javascript error on all my screens: "Uncaught ReferenceError: EPATaskbox is not defined". As if the EPATaskbox javascript code was missing.

I made sure to fully include the EPATaskbox in the dependencies, republished, but no success.

Have I missed something? Or what would be the best way to diagnose this issue?

Thank you,
