Hi- new forum member but long time NOF user here.

Tearing my hair out - can't find out why when I publish my site in NOF15 all the pages share the same top level URL.
I want to link to specific pages from my Bandcamp site, but can only get to my home page.

This is different to how all my previous versions of NOF have published. Have I toggled something, or is there a preference in place that would explain this?
I have tried changing the directory structure from 'site structure' to 'asset type' with no change. I have tried searching for an answer, to no avail.

Any help would be much appreciated.
