    When I attempted to run the in-game command /gamemode 1 on my bukkit 1.9.4 server withe the plugins World Edit, Essentials, and Landlord I received a chat message saying "an internal erron occurred while attempting to perform this command". The server log said

    [19:47:59] [Server thread/ERROR]: null

    I believe it would be fixed by un-installing Essentials, but I am unwilling to do so.

    Maybe updating essentials is enough? Are you using the 1.9 version?

    I am unable to find a download for essentials 1.9 and the launcher has not alerted me that it was out of date. If you can I would like a link for essentials 1.9. Thank you.

    As far as I know there is no offical Essentials for 1.9. There is a fork called "Essentials X" that I am aware of, but I don't know if there are more or if they will work "better". You could just try it out (AND read the page. There is some more information there)

    There are essentials "Snapshots" for 1.9. Check their Jenkins for "Essentials-2.x-SNAPSHOT.jar" and similar extensions. Works on my 1.9 server.

    (Don't think I'm allowed to link their Jenkins, just search it on Google)

    EDIT: As @I Al Istannen said, the Essentials version isn't official, there is none. There will probably be bugs, that's what a development build is for.

    Thanks all of you! I have downloaded and installed Essentials X on my server and it is working great!;)[cake][cake]
