Please provide any additional information below.
F**k my English.

Is there any errors that come up when the server starts up? I'm not sure, but I think you may have a config file issue.

No. Only when I want to create any type of warp, it gives me the error.

Here's the config:

data: connection: sqlite economy: plugin: '' base-account: '' permissions: plugin: '' warmup: notify: true cancel: movement: false damage: true cooldown: notify: true case-sensitive: false update-if-exists: false use-force-to: false show-free-price-message: false warp: defaultmsg: Dobrodosli v '{NAME}'! marker: plugin: 'null' png: marker.png visibilities: - public - global list: columns: - owner - world - location

PS: IDK why does this comment look so weird :S
