New successful install getting following error with HTTPS: Cannot write to log file: "/opt/librenms/logs/librenms.log"

Help
#1

This is a new installation using Ubuntu 18.04 and Apache. Installation was successful and also added a few devices. Upon configuring HTTPS I get the following at the HTTPS login page:

### Cannot write to log file: "/opt/librenms/logs/librenms.log"

Make sure it exists and is writable, or change your LOG_DIR setting.

SELinux not installed.

Can anyone suggest what the issue could be? Please let me know what more information I can provide.

Thanks in advance.

I couldn’t find any useful information about this error message. The Error message was not useful at all.
At the end I decided to upgrade the OS to 20.04. I’ve used 18.04 for a few years now and was confortable with it’s stability but suspected that I had mixed up the PHP versions and the OS (18.04 and 7.3 respectively). I upgrade to 20.04 and then upgraded all the PHP packages to 7.4. The error message went away. The file permissions are exactly the same as before.
