As a result of this solution http://wordpress.org/support/topic/plugin-cart66-lite-error-at-digital-product-options-for-custom-downlod-folder?replies=3 to have .htaccess file with
deny all in the folder with all the downloads, the following happens.
When I pay for a product - a zip file of mp3 for a specific CD - I can download the .zip file ok. However, I can not extract it! It will say something along the lines:
#0 Can not open file 'file-name' as archive.
I've tested the same zip in the folder without .htaccess and it all works fine.
Could you please help me out with this??? How can I protect files from accessing from the Internet, but at the same time make sure .zip are extractable when they are downloaded after paying for them?
