Hey,
so I give digital product (.zip) on my website with woocommerce. When someone download the archive then extract it, the archive turns into a .cpgz, then to a .zip again if try to extract the cpgz. Infinite loop.

I found on you forum that you had the same issue with woocommerce selling your themes and plugins
here : http://wedevs.com/support/topic/cant-upload-to-plugin-to-wordpress/

I can find many people experiencing a similar problem, but no solution.
Could you please let me know how you fixed it ?

Cheers,

Thibaud
