Whoops, the web server could not write required files to the filesystem :(

Can anyone shed some light on the below ?

which is odd because I’m seeing read/write/execute privileges

how do I proceed ?

Hello,

What is your Linux distribution?
Can you provide the result of:

getfacl /opt/librenms/logs/librenms.log
ls -lahZ /opt/librenms/logs/librenms.log

Is php running as librenms?
You can check the configuration with:

grep "user =" /etc/php-fpm.d/*.conf

You can send the result here enclosed with triple quotes so it is code formatted, eg:
```
:~# grep "user =" /etc/php-fpm.d/*.conf
/etc/php-fpm.d/librenms.conf:user = librenms
```
