The GWIOD and DR F-Lock options should be set to Turn Off Checking and Alerts. Go to F-lock and turn these options off and set the wp-config.php file option to CGI – Lock wp-config.php File and refresh your Browser. If the wp-config.php file still is not being locked then either your web host does not allow you to lock the wp-config.php file or another plugin on your website is preventing/blocking the wp-config.php from being locked. First try the steps above and let me know what happens. Also are you seeing any files being sent to Quarantine? Like wp-config.php for example. Thanks.
