    Hey guys I've been having this issue for quite some time now, and have looked over numerous threads which none seem to work, so here I am posting. The problem is when ever I finish any of my plugins and load them into my server *A Pro hosting website* they never seem to load, let alone function. I always get the same errors in console, but my Class file and Plugin.yml have no errors that I'm aware of.

    Here is the Server log:

}
    And last but not least my Plugin.yml:

    Code:
    name: JaysCC 
version: 1.0
main: me.jay.jayscc.Main
author: Jayyy
description: ChatClear

    @Jayyy Ok issue time.

    1. You are compiling with Java 8 and using it on a Java 7 server
    2. No need for enable and disable messages Bukkit does it for you
    3. Use a for loop rather than 100 lines of just send messages. It is much more efficient.
    4. The command isn't registered in the plugin.yml
    5. Always check before casting

    @Jayyy Right click your project > Properties > Java compiler > Untick the first box and change the drop down to 1.7
    it is also recommended changing your workspace compile level
