Error when install add-on


Well-known member
Hi there,

i don't know if it is an bug or not.

I have a local installation on a home server. When i try to install a new add-on i get this screen directly after clicking the button.

But the installation is ok and i have no entries in the logs. It seems something is too fast for this installation. Can anybody explain these for me?

Have you read the actual text of the message you have screenshoted? Or you saw the big bold "Error" and forgot everything in panic? :D

Because it says loud and clear: "The specified add-on is already installed". If it is already installed, there is nothing to install. You probably have installed it already sometime ago.

Are you looking to upgrade your add-on? Again the message is clear, use the upgrade page. You go to ACP - List Add-ons - [Click the Add-on name in question] - Upgrade.

@Andrej Its even not so clear. I said a "new" add-on installation. I know the difference between install & upgrade .. ;)

The error is on every new add-on installation. It is a new xenforo installation on a local server.
