Thread:Project:Support desk/MediaWiki deletes sections

I just edited Shoah (film), fixing citations in one section ("Reception"). But when I saved the edit, the whole section was deleted. I tried to re-add it, but all of a sudden another section was deleted. How can that happen? --Bender235 22:34, 7 March 2011 (UTC)

EDIT: Great, I just tried to undo all of my edits, and now the entire article was deleted. What is going on there? --Bender235 22:38, 7 March 2011 (UTC)
