Details

Description:
Despite not having EssentialsX Chat installed and using another chat plugin, using the ! prefix triggers the EssentialsX You are not authorized to shout language which means it is causing it to go through EssentialsX which it should not.
https://github.com/EssentialsX/Essentials/blob/2.x/Essentials/src/main/resources/messages_en.properties#L541

Steps to reproduce:

1. Install EssentialsX
2. On a non-OP'd user try to use ! with a message, eg. !test
3. It should return the permission denied error

Expected behavior:
If EssentialsX Chat is not installed, the shouting mechanism should not be impacted since these are sub-settings of the Chat Module

I'm seeing EssentialsChat in your startup log and in the output of your /ess version command?

I was almost certain I removed it...apparently, my eyes aren't working today. Thank you for noticing this!

😂 all good
