Ghost blog running but I get http error 502 when trying to load it. I believe it is related with ownership of /content dir?

Hi @DavidDarnes, many thanks for response when running ghost doctor I get:

✔ 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 operating system compatibility
✔ Checking for a MySQL installation
+ sudo systemctl is-active ghost_mifitnessfacil-com
Instance is currently running
ℹ Validating config [skipped]
✔ Checking folder permissions
✔ Checking file permissions
✔ Checking content folder ownership
✔ Checking memory availability

this doesn’t look good: ℹ Validating config [skipped]
do you need me to post content of config.production.json? (obviously without the sensitive data parts).
