No matter what I do, I still cannot upload a map

[GoneWithTheHuynh]

So my friends and I wanted to play an adventure map together, for example: Black Light. No matter what I do (yes i have commands on), I can't upload anything. I tried uploading zip and I tried using command method (mvimport ul <world> <link>) from the video.

Upload the world to your file manager (make sure it's unzipped)

The world folder should NOT have any spaces/special characters (so for example NOT "Adventure map", but just "adventure_map", you can rename the folders)

the command you mentioned (mvimport) is part of MULTIVERSE, install this plugin, and use the command /mvimport (world name) (world type) to import the map in your server (e.g. /mvimport mybackup normal would import the world "mybackup" as a normal overworld world)
