Invalid zip file for digital downloads
If you are experiencing downloads which generate a zip file but you or your customers cannot unzip or open the zip file, server memory is likely the cause. What often happens in these cases is your web server runs out of memory trying to build the zip file and then just stops processing it. It still gets sent to the browser to download even though it wasn’t finished.
It is recommended to increase your memory. If this doesn’t work, reach out to support and we will look into your specific setup in more detail.
