I'm using the latest version fo Sugar CRM... When I save changes to the System Settings, I get this error:

Warning: fopen(config_override.php): failed to open stream: Permission denied in /home/xxxx/public_html/crm/modules/Configurator/Configurator.php on line 63

Warning: fwrite(): supplied argument is not a valid stream resource in /home/xxxx/public_html/crm/modules/Configurator/Configurator.php on line 64

Warning: fclose(): supplied argument is not a valid stream resource in /home/xxxx/public_html/crm/modules/Configurator/Configurator.php on line 65
I have no idea where this file resides so I can't see if it even exists or is writeable...
