Everything on Level 1 renders but now any sub pages are giving a 404

Hi

I had a working page (site) for about 6 months. I upload to github and then render.com will quickly update and post to my url. (which is www.pittcooking.info)

I wanted to make some small changes and for some reason any sub pages no longer render they just give me a 404.

Looking in my public folder I have no sub folders being created either.

This is my tree structure. Anything under eg 1-burner or 2-burners etc will not render.

My git repo is private, but I think I copied it to here: GitHub - hvddrift/hugohelp

Any help would be extremely appreciated. Any extra information I can give please let me know.

Thanks in advance.
