Install own app for Confluence

[Judit Vida]

When I would like to install an app for Confluence (which was created by a colleague of mine) I get an error message: "You aren’t currently an admin of any sites. You’ll need to be an admin of at least one site to install this app." Even though I'm an admin.

Can you help how could I install it?

I had the same error, two hours later I figured out that I was trying to install it in my personal workspace and you can't do that. Create a new shared workspace and install your app, further info here
