I have just tried to upgrade an ageing site to the latest version of Modx using upgradeModx.
It was running on V 2.6.5 so I just tried to go to V 2.7.0.
It thought about it for a while, then gave me the following screen
When I click ‘back to manager’ i get a 500 error.
I checked and the PHP version is pretty old too - 5.6.
Any advice on how to fix this?
The front end seems to be working fine still.
