Solved Pex Isn't Working

Hello!

I've recently been doing some testing on a server of mine and decided to switch to Permissions Ex from LuckPerms. So far, I've had a relatively good experience apart from the fact that the plugin doesn't load when I restart the server.

When I initially install the plugin and run my server, it loads up fine. I can edit the permissions.yml and do /pex reload and the plugin will reload with all the new changes. The problem is that when I stop the instance of the server and then run it later, Permissions Ex doesn't load.

I read into the latest log and saw InvalidDescriptionException: Invalid plugin.yml (I attached the full error below)
The error then says that it was caused by java.util.zip.ZipException: zip file is empty

I should make it clear that if I reinstall PEX and then paste in my previous permissions.yml into the new one and reload the plugin, everything works. Permission Ex breaks when I restart the server.

The server is hosted on version 1.8, and I'm using version 1.23.3 of Permissions Ex.

The entire error straight from the latest log -

Code:

If you need my permissions.yml or config.yml, just let me know. I didn't see a need for them at the moment.

Thanks in advance!

Edit: When I reinstalled the plugin, I did turn off both auto updaters before restarting the server.

Seen in the final two lines of the config.yml file:

Code:

multiserver:
  use-netevents: true
permissions:
  debug: false
  allowOps: false
  user-add-groups-last: false
  log-players: false
  createUserRecords: false
  backend: file
  informplayers:
    changes: false
  basedir: plugins/PermissionsEx
  backends:
    file:
      type: file
      file: permissions.yml
updater: false
alwaysUpdate: false

Edit 2: I looked at the PEX jar file prior to starting the server and noticed that it had text inside of it. I then started the server and quickly stopped it. I looked back at the same file and it was empty.

Solution: Install the latest version, 1.23.4... I think the 1.23.3 jar is corrupted but I'm not sure.
