Minecraft Aternos server I chose the software Spigot / Bukkit, but the server complains that Worldedit doesn't work. How so?
So it would be helpful to see the log or the error message
How do I send a photo?
You can upload it to imgur and then send the link in here
Look at the last line of the error message
It says To change this, set "online-mode" to "true" in the server-properties file
OK
That has nothing to do with the error
It would be helpful if you sent the whole log and not just the one message. At the top left of the log page is a "Share" button.
So it worked for me. Worldedit / guard are running perfectly again
The online mode message is about the fact that your server is running in cracked mode and that it is unsafe. However, this does not have any influence on plugins in any way.
