I am a longtime user of this plugin. Mostly, I use it for PDFs, but I offer a few other file types as well. I recently noticed that the download I offer as a ZIP file is not downloading (see the URL I provided). When the link created by the shortcode is clicked, nothing happens.
So far, I tried turning off caching, Cloudflare, and deactivating all other plugins.
Any ideas for what the problem might be?
