The problem seems to be that the Plugins Admin doesn’t handle query string parameters properly; even the separators need to be URL-encoded for it to work.

I’ll update the PluginList (and [https://github.com/notepad-plus-plus/nppPluginList/issues/83#issuecomment-487057924|test them]) when I can, but this means they’ll only get published with the next version of Notepad++.

In the meantime, you can try to [Installation|install the plugin manually].

Nothing shows up after installing using the Plugins Admin
