Datahtms won't update - urgent

I’m trying to make urgnet changes to datahtm4 re fire information and the changes will not take in the wx.html I have tried recreating the page in FTP section and it is set to upload each 15 minutes. This has been an issue for some time, however now it has become an urgent problem.

What file are you editing?

thanks for your response. The local weather.htm page was updating but when it was uploading it changes the file name ? Where do I change that setting ?
I prefer to just leave it weather.htm and then a cron copies that to index.html on the server every 5 minutes.

I have made the changes manually at the server for now, so it is now longer urgent.
