Question ConsoleSpamFix will not work

I have got the ConsoleSpamFix plugin into the folder and put multiple different lines to mute into the config file and even 2 types of beginnings for error/warning commands. Can someone help me fix this or help me find an alternative? (Some people might say to just fix the issues instead of suppressing them but I am not going to do that because 1: I do not know how to 2: The issues don't really affect the server and it is a private server so it is not that big of an issue 3: I just want to stop seeing them or any issue for that matter.)
