I'm trying to get stack sizes to work, it's been breaking the last couple weeks honestly, but the console is telling me the permissions stacksizecontroller.canchangestacksize doesnt exist. Help?

(22:59:24) | Permission 'stacksizecontroller.canchangestacksize' doesn't exist

and another note, the data file is not showing for me to be able to set the stacks?

Usually if you get the response that a permission does not exist is because the plugin is not loaded,
try typing  "plugins" in your rcon console and see if the plugin is installed, if it isnt just install it again, if it is installed its better to just delete the data/config files and then the plugin and re install it as something might have corrupted the original file,

I personally would not grant players the ability to change stack sizes as you could very well have incredibly large stacks that could disrupt your servers running smoothly, as admin you already have the /stackall command ,

The plug in is definitely installed. I guess I delete and try again. I was just trying the permissions as a way to try and fix the stacks not working. There are no files in the data folder for the plugin either. I'll delete everything again and start over.
