That's interesting. I was asked to delete another translated page and could not. Maybe it's because you were the original author that you can do it. Did you have to do anything special?
No, I just deleted the < languages /> tag and all the < translate> and < /translate> tags. I only remove the page from the translation system and delete the Danish page the next day since I didn't know how at first, so maybe timing is an issue. Or maybe the English page has to be removed from the translation system before translated pages can be deleted?
