Simple Chinese isn't recognised?

Hi Team, recently I updated my website with Xway. (Before, I used freeway, but it doesn’t work on my new mac.) I wrote in Japanese, English, Traditional Chinese and Simple Chinese.
But via Filezilla, I cannot find the page it written in Simple Chinese.
Anyway, I uploaded the files on the server, the pages written in Japanese, English, Traditional Chinese are appeared normally, but only Simple Chinese page isn’t appeared and “404 Page Not Found” is appeared instead of it. Do you know how to fix this issue?

Hi Team, I re-edit the Simple Chinese page and re-upload all files, and the issue was fixed. Thank you. I hope you will complete Xway soon.
