Thread:Project:Support desk/HTTP 500 error when localsettings.php permissions set to 600/reply (5)

605? Seriously? Setting permissions to 605 is at least really uncommon. I do not know specific security implications, but with 605 permissions still everybody can read and execute the file. There only needs to be a security whole anywhere on the system (not even necessarily in your software, but maybe somewhere on the account of any other user) and people can directly see your data... Lower permissions for "everybody" would surely make sense.

So yes, ask them to fix the ownership of the file (btw of all your files and folders). Usual settings are:
 * owner: your personal user account (that way you can still modify the file via FTP or shell) and
 * group: the group of the webserver user (so that the webserver is allowed to access the file)
