Problema con JavaScript

[torpeman]

Hello,
I am having trouble configuring the website, both locally and when trying to preview it.
It seems to be related to JavaScript...
I have reloaded JavaScript in the Firefox browser, but the problem persists.
Here are two links to the images of the two notices that appear.
Apologies for my lack of knowledge about how to use this forum...
These are the links to the images of the two notices:

Thank you all very much!
