+## Ref and RelRef Configuration
+
+The behaviour can, since Hugo 0.45, be configured in `config.toml`:
+
+
+refLinksErrorLevel ("ERROR")
+: When using `ref` or `relref` to resolve page links and a link cannot resolved, it will be logged with this logg level. Valid values are `ERROR` (default) or `WARNING`. Any `ERROR` will fail the build (`exit -1`).
+
+refLinksNotFoundURL
+: URL to be used as a placeholder when a page reference cannot be found in `ref` or `relref`. Is used as-is.
+
