Player chat being showed twice?

So I have a problem, I installed HeroChat, and I removed essentialsChat. Then when I log on and type the chat doubles? I don't know what would cause this, but I need it fixed, my server will open soon, and I really, really need this fixed. Here is what happens:
Chat Doubles and then the plugins I use. Thanks for your time. >J<

• Delete all your plugins and add all of them back 1 by 1!

Multiverse sets per world chatting. But it is aside the normal chatting.

Since Multiverse AND HeroChat are installed, there will be 2 chats.

Go into Multiverse config, and disable the chat boolean. I think there might be a setting for MV in HeroChat, never used it before so I don't know.

His plugins are shown in the second gyazo picture.

He doesn't have to re-install his plugins.

Try deleting the prefix chat format, I know it says deleted but try it.

Look into Essentials, and look at the "Chat" section, there will be a new format generated by MV.

Change/delete/do whatever you want.

If there isn't, well then... I don't know.
