Known bug, just run Buildtools on your PC and upload the Jar to AMP

[patatas671]

i did that but i dont know where i have to put the .jar

[ThePotatoKing]

In the main server folder

Here?

That’s what I said, yes.
This also is not Hostinger support, this the forum for AMP.
Hostinger does not set their support URL in their config, so it defaults to here.
