Plugin installed, server rebooted, empty folder generates and no backpacks

[Candyxxy]

Description

paper 26.1.2 Server.

R
1.0.23
Zero Inventory Problems - ZIP Backpacks 1.0.23

using this version.

I installed it, rebooted the server and i cant craft any backbacks. I checked the plugin forlder and found the ZeroInventoryProblems folder that got generated while rebooting being empty. No config, nothing.

I've been using ZeroInventoryProblems on earlier servers before and everything was working perfectly on earlier versions. Now with this server i cant get it running. I tried to use other pb plugins cause of that, but nothing comes close to ZeroInventoryProblems. So i really wanna be using this again.

Reproduction Steps

paper 26.1.2 Server

put zip plugin inside plugin folder

reboot server

Expected Behaviour

I expected to have the folder with config files to be created, and have working backpacks
