I am new to Sitely (using v7)
I made a very simple website (3 pages) and published it. It worked fine. I made a minor change and republished and it failed !.
I discovered, by looking at the server in FileZilla, that existing pages had all been converted to 0 bytes.
I deleted these files in FileZilla and republished from Sitely and the files were restored (and the site worked again)
So, in summary: I can publish successfully by deleting existing files with FileZilla and publishing in Sitely, or by publishing to disk and then transferring with FileZilla but not directly from Sitely
Any help would be appreciated. Thank you
