Bukkit

@Androidify287

You were right!!! when i typed in java -version into terminal it said my java version was "1.6.0"

I'll try installing the development kit and see if that works.

@fireant456

jst run ur server on 1.7.5 until they come out with the updated version. people can still connect on 1.7.5

@bbalfan1

Open Terminal, and type java -version. If you're using Java 7, it should appear as java version "1.7.0", or at least have 1.7 in it. If you see 1.6, you might have to install the Java 7 JDK (Not JRE). I've had this problem before on my Mac, but installing the Java Development Kit worked out for me, for some reason.

@fireant456

Omg i am having the same problem as u!!! I cant use the portals on my server!

@Androidify287

my Mac OSX says my java version is 7, but i dont know how to uninstall older versions of java if that makes a difference

@rangewonk

Now thats a banner! :) <3

They really need to update this to 1.7.8 it only works with #1387 spigot version

when is the update coming for it to work on CB 1.7.8?

@Talamar1

It says 1.7.5 on the download link, what made you think it would work with 1.7.8?

Upgrading everything to support 1.7.8 and got this

"Unsupported major.minor version 51.0"

You're probably using an outdated Java version. MCore requires Java 7, as stated in the installation instructions.

I'm having an issue trying to get it to work. I have factions working and all that, and its ready to play. As default, it has faction.kit.fullplayer (As I have heard) which includes stuff like /f cape, and /f perm. As I am not used to such things, as I prefer the old factions plugin, I would like to remove this from players perms and make my own list. When I upload through "upload" in mcprohosting, or if I use bukget, it comes up as mcore.jar but nothing happens. When I login to the server, and type /plugins, nothing comes up regarding mcore. All I really want to know how to do is for me to manually edit players perms.

@CryLegend

Same error for me :/

@CryLegend

I am getting the same error as fcernese

"You don't have the permission to access the requested resource. It is either read-protected or not readable by the server."

@CryLegend

You don't have the permission to access the requested resource. It is either read-protected or not readable by the server.

When i try to put mcore on my server it says "error cannot load plugin mcore" in my console. this is what it looks like specifically
