    I've got this one error in my console and its a really annoying error causing the plugin to not work. It works fine on my localhost but on my dedicated server it doesn't seem to be working.
    Here is my console from my dedicated server:
    Also, I started my server using the follow bash command: java -Xmx1024M -Xms1024M -XX:MaxPermSize=256M -jar spigot.jar nogui
    I'm also using Spigot Build 1649 which is the build I want to be using for 1.7.x and 1.8.x compatibility.

    Console log:

    This Spigot build supports Minecraft clients both of versions 1.7.x and of 1.8.x.
    *** It is imperative that backups be taken before running this build on your server! ***
    Please report any such issues to http://www.spigotmc.org/, stating your client, server, and if applicable BungeeCord versions.
    *** Any bug reports not running the very latest versions of these softwares will be ignored ***


    WARNING: This build is more than 2 days old and there are likely updates available!
    You will get no support with this build unless you update from http://ci.md-5.net/job/Spigot/
    The server will start in 10 seconds!

    Where it says [18:40:31 ERROR]: Could not load 'plugins/core.jar' in folder 'plugins' --- that's the error.
    I can see its saying something about a minecraft version but i'm not quite sure. Someone help me if you could.

    If you need to see the source of the plugin just add my skype:
    assertory

    Best regards,
    Dan

    That means the plugin was compiled using Java 8. You'll need to upgrade your server's Java to Java 8 to use that plugin.
