Hi IP. To use short form refs like harvnb you need to supply a full cite, for instance {{cite book}}. You can't just put the name of the book in the edit summary. I suggest reading WP:REFB which explains how referencing works. -- LCU ActivelyDisinterested ∆transmissions∆ °co-ords° 23:27, 9 October 2022 (UTC)

Hello, I'm Pizzaplayer219. I noticed that you made an edit concerning content related to a living (or recently deceased) person on Charles III of Naples, but you didn't support your changes with a citation to a reliable source. It's been removed and archived in the page history for now. Wikipedia has a very strict policy concerning how we write about living people, so please help us keep such articles accurate and clear. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you! Pizzaplayer219TalkContribs 17:01, 13 October 2022 (UTC)
