Okay, so it made all the saved worlds show up in the webUI, but now none of them will start. I downloaded the latest JAR file for the server, but when I select each one’s profile and runnable jar file to the current server version, it just doesn’t start.
Considering I had to download1.13.2 after the webUI started working and the worlds loaded in the webUI, I tried changing the version to 1.13.1 instead because it was already present before I downloaded 1.13.2. But neither version made the world start. I’m at a loss now.
