Drupal 8 Status Report Errors

Hi,

My Drupal 8 status report is giving me warnings:

The first relates to protection of configuration files:

Configuration files Not protected
Protection disabled
The file sites/default/settings.php is not protected from modifications and poses a security risk. You must change the file’s permissions to be non-writable.
The file sites/default/settings.local.php is not protected from modifications and poses a security risk. You must change the file’s permissions to be non-writable.
The file sites/default/services.yml is not protected from modifications and poses a security risk. You must change the file’s permissions to be non-writable.

However, permissions are as shown.

-r–r–r– 1 root root 6761 Mar 27 12:57 services.yml
-r–r–r– 1 root root 3754 Mar 23 09:16 settings.local.php
-r–r–r– 1 www-data root 30819 Mar 23 08:59 settings.php

I’ve restarted apache and rebuilt permissions & cleared cache but the warning stays even though the files are not writable.

There is also a warning:

Rebuild access Enabled
The rebuild_access setting is enabled in settings.php. It is recommended to have this setting disabled unless you are performing a rebuild.

However there is no rebuild_access setting in setting.php.

Any help appreciated.
