The plugin 'Multiverse-Portals-4.0.0' could not be loaded. in the log
the logs normally give solutions for these kind of things. I will help you with the access nodes tho.
To give access nodes to people, you will need a permissions plugin. I personally recommend permissionsex and so i will give you a few steps for that
1. install permissionsex - https://aternos.org/addons/a/bukkit/permissionsex
2. install vault ( permissionsex depends on it ) - https://aternos.org/addons/a/bukkit/vault
3. restart your server ( or start it if its offline )
4. go to the console https://aternos.org/console/ and type;
pex user ( username ) add permissions.*
5. go back to your server and type /pex group ( group ) add multiverse.access.WORLDNAME
Remember
the default group is called default. people should be added to it automatically.
WORLDNAME in the permission node multiverse.access.WORLDNAME should be the name of the world you want people to be able to tp to
