Solved chat and essentials commands not working

[SOLVED] so, i just made a new 1.12.2 server and am having some problems when using essentials. when i join the game, chat says "Essentials failed to load, read the log file." leading me to believe this most likely is a problem with the main "Essentials.exe" file. when i use chat, the ingame chat says nothing. when i do the other commands, the ingame chat says "An internal error occurred while attempting to preform this command". this seems to only happen when i use commands for essentials and when i use the /help command. The plugins i use are world edit, anti cheat plus, and of course essentials, although i have tried this without any other plugins and the same thing happens. in this log i use the the /say command to show what i am doing.

This is the log.
