Freshly installed Spigot 1.15.1 that i made with buildtools, got the old groupmanager/ folder and jar file and vault/cmi and luckperms

after the server started up once, i /stop it, started it again.

then typed in-game lp migration groupmanager true, and it looks like it's doing a bunch of groups and users. but the console is flooded with exception errors.

-latest.log removed-

Not sure what i am doing wrong, we've always had groupmanager on this small server and it was time with 1.15.1 to move to luckperm.

Your latest.log does not contain any errors.
Also, https://hasteb.in is prefered over downloading a file.

Oh for cryin... i dunno how the wrong one ended up there, i am sure i checked before including it..

ok - trying again

Do you use GroupManager from EssentialsX or the original one?
Because I think the original one might not even work with LP.

This is the one i had working okay on my spigot setup for 1.15.1,
https://www.spigotmc.org/resources/groupmanager.38875/

If you prefer i use a different build for 1.15.1 feel free to link to it, ill try that instead.

Looks like ther isn't even a build from the EssentialsX team

Also, that version you use seem strange and not like the original one either, so perhaps the issue is changed API stuff by that dev?

I can only suggest to use the original one to make sure it's really supported by LP.

Ok, feel free to link me to the one that luckperm supports, and i will try to work it with that one.

Try the latest LP from here: https://luckperms.net/

Should be fixed already.
