Ok I tried upgrading my 2.2.2 to 2.3.1. I brought this site over from a staging server which I originally tried it on. Did the upgrade using the instructions from the User Guide. It doesn’t look like either the front-end or the control panel want to call the jquery libraries. I am going through all of the checks suggested throughout the forum to make sure cache is clear, that I have loaded the new themes folder, no special variables etc.
I can’t provide a sample as this is internal.
The source on the Control Panel side throws this for at the bottom of the document:
