I installed luckperms to my server hosted by akliz and made sure the config file was h2. So I didn't change anything.
When i try to join the server i get A database error occurred whilst loading permissions data.

Server type: spongeforge-1.12.2-2838-7.3.0.jar
Version: LuckPerms-Sponge-5.2.26.jar

Could you please provide a full start up log

I updated the bytebin link. It should contain the full startup log

What version of LP/Sponge are you using (probably should have followed the issue template).

This has definitely been fixed in the latest version - I suspect you may in fact not be using the version you think you are.
