title: '`next-head-count` is missing'
---

## Why This Error Occurred

You have a custom `pages/_document.js` that doesn't have the components required for Next.js to render correctly.

## Possible Ways to Fix It

Ensure that your `_document.js` is importing and rendering all of the [required components](/docs/pages/building-your-application/routing/custom-document).

In this case you are most likely not rendering the `<Head>` component imported from `next/document`.
