It might be your chat plugin.

If you have essentials/essentialsx you need to download essentials chat/essentialsx chat

That doesn't make any sense. If they have a chat plugin that fine.

Unfortunately PermissionsEx is currently unmaintained and no further updates are planned. Because of this, all issues are being closed. If you are looking for an actively maintained permissions plugin, take a look at LuckPerms. It is compatible with major server platforms and can import data from PEX.
