Find this block of code:
<?php
// WA eCart Redirect
if ($WBW->redirStr != "") {
header("Location: ".$WBW->redirStr);
}
?>
and modify it to look like this:
<?php
// WA eCart Redirect
if ($WBW->redirStr != "") {
die($WBW->redirStr);
header("Location: ".$WBW->redirStr);
}
?>
This will print out the redirect string to the page and stop execution. Can you post back with what is on the screen when you go through updating?
