The "essentials.jump" permission stopped working after that I updated from #189 to #194. When they have the permission it says "You are not permitted to do that. Are you in the right mode?"

How shall I fix it.. I'm not a coder. This is the place to report bugs in isn't it?

Yes it is, you are simply not in a position to write "Fix this!", nobody will follow your order. This is not how this works.
You can either a) pay somebody to fix it for you, b) fix it yourself, or c) wait until somebody takes care of it

Alright thanks. I'll wait some weeks for this fix then.

We haven't changed anything regarding /jump compared to upstream, so it's not our issue. Your entitled attitude isn't helping.

Fix this! I've waited for 20 days!!!

Fix it yourself. You are in no position to demand service.
