Server operating system? What have you done recently that might be to blame? (Recent upgrade?) Is this the first error message in the logs? (It’s usually the first problem.) Any luck with ‘ghost doctor’ ?

Is that index.js file at that address? If it isn’t, is it supposed to be, or do you have a mismatch between your configuration file and your actual directory structure?

Wait, hang on a second. Normally one starts ghost with ‘ghost start’. What set of directions are you following that you’re starting it this way?

Ghost doctor shows this:

Checking system Node.js version - found v16.17.1
Checking logged in user
Ensuring user is not logged in as ghost user
Checking if logged in user is directory owner
Checking current folder permissions
Checking system compatibility
Checking for a MySQL installation

• sudo systemctl is-active ghost_kigalian-com
  Validating config
  Checking folder permissions
  Checking file permissions
  Checking content folder ownership
  Checking memory availability
  Checking binary dependencies
  Checking free space
  Checking systemd unit file
  Checking systemd node version - found v16.17.1

It refused to restart after an upgrade, then I downgraded.
