Unsupported API version in the stack trace
Symptoms
- The plugin fails to load at server startup
- In the log: “InvalidPluginException: Unsupported API version X”
Cause
The plugin's plugin.yml specifies an api-version newer than this server supports: the plugin was built for a newer version of Minecraft/Paper.
Possible causes
- A plugin build for a newer Minecraft version was downloaded
- The server has not been updated, although the plugins have already been updated for the new version
How to fixMedium risk
- Compare the version in the evidence (
Unsupported API version X) with the server version (/version). - Either download the plugin build for your server version (the Versions section on Hangar/Modrinth/SpigotMC), or update the server to version X or later (with a world backup and checking the other plugins).
- Restart the server.
