I've been troubleshooting this problem since yesterday. I try to send the Subscriptions XML Datafeed to a script on my client's server. All the script does is capture the encrypted file for later processing. It stores the file in a folder. But the file isn't showing up when I send the datafeed to the script. Long story short, I finally did a var_dump of the $_POST data coming in from Foxycart, and the array is empty. No $_POST('FoxySubscriptionData'), no nothing. (parentheses used instead of brackets to get around BB code)
If you guys could help me get to the bottom of this asap, I would really appreciate it. I'll whisper the store info.
