I have a test instance of NC15 on a Shared Hosting.
Works pretty well, but after the last major upgrade I got warning about missing db indices and others.
I have no shell access for that instance.
Some days ago I discovered the App “OCC Web”. See
Enable this app and type your commands.
Help is integrated.
Disable it afterwards and you are done.
No need for SSH.
Tested on Hetzner and 1und1.
btw. Repeating (history) is available. Cool
