Do you have your site source somewhere where I can have a look?

Do you have your site source somewhere where I can have a look?

That's a private repo. But I have successfully reproduced it in the following steps：

1. Create a new site: hugo new site .
2. Download hermit theme.

hugo new posts/first_post.md
hugo new posts/_index.md
hugo new _index.md

4. edit config.toml

baseURL = "http://example.org/"
languageCode = "zh-cn"
title = "My Site"
theme = "hermit"
hasCJKLanguage = true
copyright = ''

enableRobotsTXT = true

pygmentsStyle = "solarized-dark"
pygmentsCodeFences = true
pygmentsCodefences  = true
pygmentsUseClasses  = true

[[menu.main]]
    identifier = "posts"
    name = "Posts"
    url = "/posts"
    weight = 2

[author]
    name = "Tnze"

[params]
    author = "Tnze"
    bio = "There are 10 kinds of people in the world, one knows binary, the other don't."
    subtitle = "Record what I learned at ordinary times"
    homeSubtitle = "Record what I learned at ordinary times"
    
    dateform        = "Jan 2, 2006"
    dateformShort   = "Jan 2"
    dateformNum     = "2006-01-02"
    dateformNumTime = "2006-01-02 15:04 -0700"
    themeColor = "#494f5c"
    footerCopyright = ''

And then it's panic.

I am waiting…… ʕ •ᴥ•ʔ
Should I package and upload this test site?
I think this must be a bug.

[Tnze]

The source code of the website can be downloaded from this temporary link: site-test.7z

@Tnze It's not like we/I work on this project 24/7. We will eventually get to this. Until then I suggest you use an older Hugo version.

[Tnze]

I see. Thanks for your help. ^_^

It is a bug, and I will fix this, but having the home page as draft=true is rather unusual. If you remove that draft flag it will work.

Note that before the latest release we did not care about the draft flag on list pages, now we do.
