Well. I have moved our website hosting to siteground and installed the latest version of your Treasury "the one that didnt include the pictures

".
When i test the IPN link i get this error
Premature end of script headers: /home/fullcon1/public_html/main/components/com_mh2treasury/ipn/ipnppd.php
It is a 500 Internal Server Error ALONG with a 404 error. here is a link to the IPN test
