Hello! My server is using Paper 1.15.2 and we have the latest version of multiverse core, portals, and nether portals. But the plugin is disabled and we cannot go to the nether through a different world(survival1), it leads us to our default world(spawn). Is there a solution to this, or is the plugin broke? Thanks! (i uploaded the log, if that helps)

we have the latest version of multiverse core

That's not what your log says:

[20:15:40] [Server thread/INFO]: [Multiverse-Core] Loading Multiverse-Core v3.0.0-SNAPSHOT-b760

[20:15:59] [Server thread/ERROR]: [Multiverse-NetherPortals] Your Multiverse-Core is OUT OF DATE

It looks like your Multiverse-Inventories plugin is old too. I don't know if that matters, but the outdated Multiverse-Core definitely does.

you can download the latest version of all mv plugin here: (supports 1.15.2)
