Flex应用程序在本地工作,在线时失败(连接到PHP脚本以将行插入到DB中)

I've got a Flex application that works wonderfully when I test it on my machine locally. It uploads files and send variables to a PHP script (that inserts them into a DB) with no errors when I run it locally. As soon as I put it online, the upload continues to work but something between my Flex application and the PHP script fails because no data is committed to the DB. I know the PHP script works fine - not only does it work when I run the Flex application locally but when I go directly to the PHP file online, a new empty line is added to the DB.

I initially thought that this was a cross domain issue so I added the following to the root of my hosted account:

<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*.MYURL"/>
<allow-http-request-headers-from domain="*.MYURL" headers="*" secure="false"/>
</cross-domain-policy>

I based this off of what I found online which seems to have done nothing for me. I'd also be happy to provide an error message but I don't get one when I debug.

Any thoughts would be greatly appreciated.
