I've looked in the server error log and this is what is displayed
'[Tue Jun 09 08:53:22 2015] [error] [client 86.2.129.58] SoftException in Application.cpp:603: Directory "/home/wwwcctvhdsystems/public_html/modules" is writeable by group, referer: http://www.cctv-hd-systems.co.uk/order'
This has to be to do with permission but changing the permissions on payment.php seems to make no difference.
Help
