The favicon is not working.

[DominoKorean]

Describe the bug

I followed the instructions in the official VitePress documentation to add a favicon, but it doesn't seem to be working.

Reproduction

• I added this to my config.mjs:

  head: [['link', { rel: 'icon', href: '/favicon.ico' }]]

• I placed the favicon.ico file inside the /docs/public directory.

Despite this, the favicon does not show up in the browser.

To troubleshoot the issue, I also tried the following:

1. Setting the base and updating the favicon path accordingly:

   head: [['link', { rel: 'icon', href: '/doc-blog/favicon.ico' }]]

2. Trying this path instead:

   head: [['link', { rel: 'icon', href: '/docs/favicon.ico' }]]

3. Hard reloading the browser with Ctrl + F5.

Currently, the site is deployed via GitHub Pages, using a repository named doc-blog without a custom domain.
Here is the repository: https://github.com/DominoKorean/doc-blog

Expected behavior

The favicon should appear in the browser tab when visiting the site.

You've put head inside themeConfig, it should be outside.

    head: [['link', { rel: 'icon', href: '/doc-blog/favicon.ico' }]]
    }

should be

    },
    head: [['link', { rel: 'icon', href: '/doc-blog/favicon.ico' }]]

Ah,
I actually tried that approach before uploading the issue
but at the time, I only tested /favicon.ico and docs/favicon.ico, and didn’t try /doc-blog/favicon.ico.

Thank you for your help!
