Hi,
I bought both version of the book (1st, 2nd) and the electronic version of the second version too, awhile ago.
In second book, I'm trying to modify the script (add_pdf) in the first site (selling virtual products) to add image instead of pdf, by using the script (add_other_products) in the second site example (selling physical product)
Here, I upload my modified file (add_pdf).
Everything goes fine when I upload an image, but for some reason I cannot view them.
I keep getting the error from the script view_pdf (first site): "This page has been accessed in error."
