Latest Zara not uploading index file

[ripfree]

Lastest Zara Premium gave me access violation errors when publishing. I had no idea what was wrong, but I assumed the issue was an incompatibility between my web design and the new Zara version. So I rebuilt the website, this time using a template. (as it turned out, the access violation was the host changed the FTP hostname). No issue, the site needed cleaning up anyway. But now the new website won't upload an index file, I guess leaving me with "blank_html" on the host server. Also, all the files go to a folder called "blank_html_files". And the index file is "blank_htm" too. Or "blank_html". I've looked at these so many times I can't remember. Either way, blank isn't working. Please help. This never happened before, what has changed?
