Nodeum Web interface is not available. You can access the system via terminal but not via the Web interface.
You have some error message such as :
Check logs in : /opt/nginx/logs/error.log . You can see some permission error messages in the Nginx logs. Permission denied for Passenger - folder tmp.
This can occurs after a Nodeum version upgrade.
Root cause :
The problem is due to a permission mismatch of the tmp folder.
Verify the user ownership of the subfolders of : /home/nodeum-nginx.
You will see that the /tmp folder has different user ownership.
To solve this problem , update the user ownership :
chown nodeum-nginx /home/nodeum-nginx/tmp -R
