/wp-config.php file is writable

Recommendation from WP Hide Ghost:

Try setting chmod to 0600 or 0640 and if the website works normally that's the best one to use.

@marcusquinn this might need a bit more context

Be aware plugin like caching plugin need right to write in wp-config

In any case hiding a WordPress is way more far complex then editing few files.

You have, at least, to move out uploads, plugins and theme from wp-content/

And stripe a lot from the head I do usually that by making a child theme:

In managed WP, the file is not writable.. But in Developer edition, a user has to change that file themselves, from the filemanager. This is by design though - the developer edition is vanilla and developer sets it up as they see fit.
