there are a number of diffeant things that cause the upload to fail, to trouble shoot, follow these steps:
1) find the following code:
if ($WAFV_Errors != "") {
PostResult($WAFV_Redirect,$WAFV_Errors,"index");
}
and change it to:
if ($WAFV_Errors != "") {
die($WAFV_Errors);
PostResult($WAFV_Redirect,$WAFV_Errors,"index");
}
2) add the following code at line 1 to turn error reporting on:
<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>
3) Open the bindings panel and expand the WA Uploaded Files Global Status group and add the debug info binding to the page.
post back the results after trying an upload, this will help me determine what the cause of the problem is.
