A liquid-thread message was place on a page that was problematic for me, so I moved it to my user talk space so that I wouldn't forget to deal with it. That left a placeholder comment on the original page, so this is just as problematic as the original message. I no longer need the original message, so both could be deleted. The problem is that I can't find a any safe way of getting rid of the placeholder. When I deleted it I lost both content and theming of the page, and had to revert.

There must be a safe way of doing this. Can anyone help?
