Oh sorry, yes, it is a new server.
I didn't change anything before, its software was Mohist to use plugins and mods at the same time.
I wanted a server in the 1.18.2 to play with friends who have Minecraft bought and also some of them who haven't done that.
We tried later to initialize it without pluggins and then it worked, but we want the skin restore plugin to see all the skins.
Is it not shared? I copied the link.
