Can't Backup Business File on Server Edition

I am using Manager Server Edition 20.10.89 on Windows 10. I cannot back up my business files. I get an HTML file when I want to back up any of my business files ie backup-download.html It’s no longer backing up in the usual *****.manager file.

@lubos kindly look into it for me. Thank you.

I’m not able to reproduce the issue. What is your web-browser? Also, does this happen on every business?

Am using Google Chrome. Yes, it happens to every business.

I’m not able to reproduce the issue. What if you try another web-browser such as Firefox?

It worked fine with Opera Mini Browser. So I guess it is browser-specific issues. Anyway, what might have caused that in Google Chrome for it to behave like this all of a sudden?
