Warning: I am able to write to the configuration file: /home/xboxmemb/public_html/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

using ftp i have changed the file permissions only for them to revert back??
