Please explain your issue. How do you trigger it?
I installed the latest version of the plugin to test LuckPerms support, but I get an error when starting the server.

Are there any errors in the console? Please use: https://pastebin.com

I have the same issue both on 1.14.4 and my 1.15 paper v8 test server. Is it to do with LPv5 rather than v4. Do you need version 5 of LP to use 4.4.6?

I do not understand you very much

Sorry, I was just adding that I am getting the same errors as you. I tried the plugin on 1.14.4 paper and it failed to work, then also tested it on 1.15 paper #8 with luckperms v5 and it also failed to start. I think it has something to do with the changed Luckperms API. That is what i was trying to say

I have the same issue, i am on a 1.8.8 server.

You must use the dev version of luckperms.
