Hey guys, So because 1.19.4 is a fairly new version of Minecraft, not many plugins supported this version until I finally decided to change it down a version to 1.19.3 so most of the plugins I relied on actually worked in my server. The problem is that it won't start after I pressed start on the dashboard. Here's the error:

I am having trouble trying to get the amount of kills a player has gotten on the scoreboard. Is there a command to that and if so, what is it? I have tried %killstats_kills% and a bunch of other commands and they all dont seem to work.

I am having a problem with my chat. When I first started my server, I put the following command into skript, on chat: if a player is op: set chat format to "&4player%&r: %message% I deleted this skript after installing powerranks to do my rankings. However it seems that the skript saved and affects my ranks with the red name. It looks like this colliding with powerranks... Players who aren't op dont get this because of the "if a player is op" section of the skript... Is there a way to recover a deleted skript? or some way to reset that certain skript? I have tried restarting the server, reloading powerranks and reloading all of skript. Any help will be appreciated...
