New error in server log

No problem. Hope after that, basic commands work again, too. Not even /help or /fly work atm. Will update soon.

Edit:

Updated the plugin, everything is fine, with LastSeen at least. Curiously. I have not changed anything else, and since the latest update the /fly command seems to be entirely gone. I do remember using it recently with this setup, to avoid switching gamemode just for that. Somehow it's just ... gone.

The /fly command moved to Essentials some time ago.
