I setup opernfire version 4.0.1 and also installed others plugins and display in plugin list but only restAPI plugin 1.2.5 installed successfully not show in plugin list.
I see in my plugin folder of openfire show restAPI folder..
Minimal version for the REST API 1.2.5 is: Openfire 4.1.0
You could manually try the plugins here , which comes from our Bamboo instance building from the 4.0 branch on github
Thanks for support.But I have download old api version from my current exitsting openfire setup.it work fine.
