Error: Deprecated DisqusShortname Prevents Site from Building in Whiteplain Hugo Theme

[robotAstray]

Description:

While using the Whiteplain Hugo theme, I encountered an error related to the deprecated DisqusShortname. This error prevents the Hugo site from building correctly.

Steps to Reproduce:

1. Create a Hugo site using the Whiteplain theme.

2. Run the following command:

   hugo server --buildDraft

3. The site fails to build, and the following error message is seen.

Error:

```
ERROR deprecated: .Site.DisqusShortname was deprecated in Hugo v0.120.0 and will be removed in Hugo 0.134.0. Use .Site.Config.Services.Disqus.Shortname instead.
Built in 12 ms
Error: error building site: logged 1 error(s)
```

Expected Behavior:

The site should build successfully without any errors. The theme should use the updated property .Site.Config.Services.Disqus.Shortname instead of the deprecated .Site.DisqusShortname.

Environment:

• Hugo Version: 0.134.0
• OS: macOS

Proposed Solution:

Replace the deprecated .Site.DisqusShortname with .Site.Config.Services.Disqus.Shortname in the layouts/_default/single.html file.

I have opened a PR to address this issue: #34

@robotAstray
Thank you for your PR. Sorry for the late reply.
I would like to merge your PR, but I don't want to change the text color. Could you please revert style.css file change?

[robotAstray]

@taikii yes of course! I changed it for my work and forgot to change it back. I will fix that now.
