    With debug on, when plugin is activated this error message appears:

    The plugin generated 578 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.

    It’s not new, I’ve seen it in years when debugging, so I can’t say when it started.
