On Linux/UNIX systems, navigate to your Sugar installation directory. You can see the current file permissions of the config.php file with this command:
# ls -al config.php -rw-r--r-- 1 nobody nobody 2485 18 Apr 18:06 config.php
To change the file to unwritable, use this command:
# chmod 444 config.php
Then confirm the file permissions have changed by using the first command again:
# ls -al config.php -r--r--r-- 1 nobody nobody 2485 18 Apr 18:06 config.php
The warning message within Sugar should no longer be present.
