Apologies -- that was a bug in the initial 1.3.7 code-release. The patch to fix that is in this thread: (you only need to apply the most recent edition of the patch, but will need to remove and re-install the PP module for it to take effect)

i am a ok with computers but i don't know how to fix these patches soo my paypal works can somone help me please :lamo: :frusty:

You have somehow copied the **/ipn_main_handler.php **file into the **/includes/modules/payment **folder.

You need to delete that file.

1. Instructions on installing the patch:
   http://www.zen-cart.com/forum/showthread.php?p=365905#post365905

2. Take a careful look at the folders contained in the zip file. There are 11 files, and each of them belongs in a specific folder.
   Remember that some of the files have the same "name", but are for different folders.

You need to keep the entire structure intact. If you're not sure whether your FTP program can handle the folder structure, then upload each file one at a time into the prescribed folder.

In EACH case, you should actually be replacing another file ALREADY on your site with the updated version of the file from the patch. If there's no file already there by the name of the file you're uploading, then you're putting it in the wrong place.

ok i downloaded all of them.... but my internet won't let me open them.... and how do i use ftp to upload them i don't understand...... is there soomone more qualified to do this.... maybe????
