When I undid it, still the above message remained when website was downloaded. I wonder what can i do?

Hello ZenArtMan,

On the very bottom of the file:
/includes/classes/shopping_cart.php

Remove the extra blank lines !!!

I just had the exact same problem after I altered things this morning.
Quickly deleting those blank lines worked wonders for me !

Bang!. You made it work. Thank you very much. This FTP program is something that I am not completely accustomed to still.

No problems !
I personally use CutFTP Pro editor - and I even came up with the error, editing on the server :(

I'll remember to check the bottom of all files next time however !

Have a great weekend !

1. Editing on the server will often end up leaving a blank line at the end of files.

2. CuteFTP is moderately reliable. I find FileZilla to be flawless in terms of reliability.
