Direct answer

Use the parser’s file, line and column as the starting point, then inspect that line and the lines immediately above it for bad indentation, tabs, missing quotes/colons, or invalid structure. Restore a known-good config if the plugin regenerated a broken file.

Diagnosis to use: A YAML parser location refers to the text format, not necessarily a plugin bug or a missing permission.

What it means

YAML is indentation-sensitive, and tabs, missing quotes, or malformed lists can stop a plugin from reading its config.

What to collect: Copy the file before editing. Look at the reported line and preceding indentation: tabs, unquoted punctuation, mismatched quotes and lists nested at the wrong depth are common. Use a YAML-aware editor to reveal spaces.

If you are a player

  • Record the exact command/message or feature that failed and the time it happened.
  • If the problem affects only your account, note your permissions/group and whether another player can use the same feature.
  • Send the owner the exact wording rather than repeatedly retrying; plugin startup/configuration errors must usually be fixed server-side.

If you run the server

  1. Stop the server/plugin before editing and use the parser’s file/line/column or the plugin’s first configuration error as the starting point.
  2. Compare the file with the documentation for the exact plugin release; keys/defaults can change between versions.
  3. Restore a known-good config or regenerate on a backup/test copy if structure is badly damaged, then reapply changes in small groups.
  4. Avoid tabs/invalid YAML structure and avoid copying configuration from a different plugin/version without checking its schema.

Targeted repair: Correct only the syntax error and check the plugin’s own config schema; a YAML file can parse successfully while still containing unsupported keys. Restore the last valid config if multiple errors are present.

Verify after the change: Restart the plugin/server as documented and verify that the original setting actually takes effect; no parser exception should remain.
