@shubibble Have you uninstalled PluginManager plugin?

[shubibble]

Hello!

@deefrawley I'm sorry as I am unfamiliar with Flow Launcher and GitHub so I only followed the window popup that showed. I also don't know where the new issue template might be found.

@Jack251970 I think I did try installing PluginManager but I can't seem to find where to uninstall it.

[Jack251970]

@shubibble Could you please check if you have this item in Plugin page?

[shubibble]

@Jack251970 sorry for the late reply, but no I don't see it there. I even tried looking it up in the Plugin Store and it has the option to install it. I don't know if this is helpful but when I go to the Plugin Store I often have to refresh before anything comes up.

[shubibble]

Should I just delete all my mods or reinstall?

[Jack251970]

@shubibble Now I know the reason you encounter this issue. Please reinstall Flow.Launcher because that plugin is for installing plugins.

Hi! I reinstalled Flow Launcher from here: https://www.flowlauncher.com/ and I believe it is now working. I tried downloading a plugin and it just installed it! May I ask what caused the problem so I don't do it again?

Thank you very much!!

Please do not uninstall Plugin Manager plugin. It is a core plugin for managing plugins for now. (In future, we will put plugin management feature inside Flow Launcher and you can do that)
