We upgraded a site from 5.14.x to 5.16.3 and we are now seeing strange issues where some data is clearly in the system but it is not showing on the screen.
For examples, if you edit an address you can see the address on the screen before you edit it and you can see the lat/long data when you edit it but you do not see any of the other fields filled in.
The data is all in MySQL.
Also, we have an event in the system. We need to edit the Info and Settings tab. This tab loads blank.
All of the other tabs are fine.
We tried to create a new event and also get a blank screen.
Thank you in advance for your help.
