Hi Fang_Langford, and welcome to Tikiwiki community!
You are right. It's fixed back again.
I posted a comment there explaining (there is a user aiming to contribute greek documentation, but that user didn't learn how to properly create a new (for translation) page and link it to a page of that translation set.
Maybe we should improve documentation about this process? (what do you think? Suggestions for new-comers to Tikiwiki multilingual site?)
