Hi!
I’m having the same problem on my site using Polylang and EBD. With Polylang activated, the download links don’t work and I’m redirected to a page telling me that the download cannot be found. When I add either a /en or /de (english or german) to the url on that page, the download works. I’m not a strong programmer so I’m not sure what I would need to do for the site to know to navigate to the url with the language tag included. I’ve tried setting the endpoint to en/download in Download Monitor settings but I get the same result. I’ve also tried tinkering with the settings of Polylang and Download Monitor including allowing Force Download without success. I’ve also uploaded all the files via the WP Media Uploader and inserted the url into Download Monitor manually but without success.
