I uploaded this file and the cart worked. However, when I edited a text field on the cart.php file I received the same error again. Strangely when I undo the adjustment and upload it again, it still fails. The only way to fix it is to go to backups and download the exact file before it is every changed. This is happening with all the files associated with the ecart process. See the test I did below. The only change on the "-bu" files and uploaded it. It fails. see pm
