DevGuy,
I had some trouble with this also. This php code that was posted to the forum did work out of the box. Two questions, one did you use the following code? And, do you have write permissions to the directory you are posting to?
Here is the original code I used for posting:
<?php
date_default_timezone_set('America/Chicago');
$outp = fopen("../teddata/xmlfile." . date("YmdHis") . ".xml", "w");
fwrite($outp, $HTTP_RAW_POST_DATA);
fclose($outp);
?>
Lastly, what type of server are you on Windows / Linux / Apache / IIS? Is it shared hosting provider or you server?
