    Hello! Thanks for looking to help me. I am currently developing a plugin. It is going to be a private message plugin. So when the user uses /private <player> <message> It will send a message to the player provided. It will come up on the receiving player's screen as <sender>: <message>. I want to be able to allow the player to set that in the config file. I will then replace <sender> with the sender's name. The problem is that if you try to do this.getConfig().getString("from") it sends errors if the string contains any non alphabetic or numeric characters such as < or -. How would i get any characters from the config?

    Note: I will add the method that replaces color codes with ChatColors and <sender> with the sender after i get it to work.
    Code Examples:
    Usage of getConfig().getString():
    Code:java
    1. recipient.sendMessage(this.getConfig().getString("from") + message);


    Error in console:
    Code:
    [WARNING] Unexpected exception while parsing console command "private $console Hello"

    np15isntboss What is line 31 in Tell.java? (a larger code snippet is preferred)

    Sorry for not adding more code and I think I may have copied the wrong error message >.>

    Revised Code (hopefully enough this time :) ):
