I keep getting this message on my site:

Warning: I am able to write to the configuration file: /kunden/homepages/23/d113818184/htdocs/spot/shop/includes/configure.php. This is a potential security risk - please set the right user permissions on this file (read-only, CHMOD 644 or 444 are typical). You may need to use your webhost control panel/file-manager to change the permissions effectively. Contact your webhost for assistance.

I have the config file set to 644 and get the message. If I set it to 444 it doesn't show it but why for 644 when it says it is okay.
