I updated everything and still it doesn’t work. After hours of debugging, I found that Download Manager is actually conflicting with its own addon, so I had to deactivate the Premium Packages – Sell Digital Products Securely plugin in order for Download Manager to “work”. But when I tried to visit my downloads again there were now only showing blank pages. Then I realised that every file’s template setting has been reset, maybe because you renamed the templates. So now its been 2 hrs since I started setting the template setting manually for more than a 100 files that were resetted. It will take me days to go through all the download files selecting again the templates that you reset, because your half baked plugin doesnt have a bulky option for such important setting.
