Problem
I first found this issue when updating a new site from 0.8.0 to 0.9.0, first on my own fork, then reconfirmed using the direct from this repo.
Steps to recreate:
hugo new site docs&cd docs
Congratulations! Your new Hugo site was created in /Users/carl/Projects/temp/docsy-plain-test/docs.
Just a few more steps...
1. Change the current directory to /Users/carl/Projects/temp/docsy-plain-test/docs.
2. Create or install a theme:
- Create a new theme with the command "hugo new theme <THEMENAME>"
- Install a theme from https://themes.gohugo.io/
3. Edit hugo.toml, setting the "theme" property to the theme name.
4. Create new content with the command "hugo new content <SECTIONNAME>/<FILENAME>.<FORMAT>".
5. Start the embedded web server with the command "hugo server --buildDrafts".

Total in 6 msI've tried this on about 5 different sites (old and new) and it all narrows down to setting the type: docs, and this partial coming up as the fault. I haven't yet found a fix... but I'm puzzled as to if I'm the doing something wrong to have been the first to report this...?
