Front End Script Runs on Multisite After Upgrade

I just upgraded my multisite to the latest version and it was not entirely pain-free!

1. After I upgraded, somehow it network deactivated itself although appeared to be activated still on several network sites individually

2. As I loaded the front-end of each network site I was shocked to see the following codes running in the header (I had to go through every site for it to run these as me, so as not to risk end users seeing them). This was all showing up in the header of each website:
