I know this issue has been mentioned before, and you say 'to contact your server about sending weird HTTP headers accepting POST requests'.
I need a little more information about this please if you can? Which headers specifically cause problems (contacting my server will be much easier if I know which ones have problems)? How do I even find out what headers my site is sending/accepting? (http://www.energywiseoz.jebwebsolutions.com.au/get-your-free-report/)
