I switched from version 1.14.4 to version 1.15.1. Groups were deleted after upgrading to version 1.15.1. When I checked the Luckperm files, I found that the size of the database file was too small.I have a backup system and I installed the luckperms database file from the backup system I used in 1.14.4 while the server was off. I ran the server and the groups came back, there was no problem, then when I shut down the server again with the stop command, the groups were deleted again.

The database is deleted when I turn the server off and on. 1.15.1

Luckperm version : LuckPerms-Bukkit-5.0.39

Luckperm config:

config (3).txt

Server version : 1.15.1 Paper #32

Hey, just to be clear - when you upgrade your server version from 1.14 to 1.15 the groups disappear - or are you talking about upgrading from LP v4 to v5?

I'm already using version 5, I'm constantly use latest the plugin. I didn't new update the plugin. I just upgraded the server from 1.14.4 to 1.15.1.

Could you try the upgrade again. The server version should have no effect on the LP storage system.

İ have fixed this problem. İ removed lib direction and reload, it is fixed.
