# Troubleshooting Nuxt SEO Utils

[Copy for LLMs](https://nuxtseo.com/docs/seo-utils/getting-started/troubleshooting.md)

## [Common Issues](#common-issues)

### [Meta Tags Missing in Production](#meta-tags-missing-in-production)

**Problem:** Meta tags work in development but are missing in production.

**Solution:** Check the following:

1. Ensure you're using SSR (not SPA mode)
2. Run `pnpm build` and check the generated HTML
3. Enable debug mode to see what's being set:

nuxt.config.ts

```
export default defineNuxtConfig({
  seo: {
    debug: true
  }
})
```

### [`lang` Attribute Not Applied](#lang-attribute-not-applied)

**Problem:** You set `htmlAttrs: { lang: 'ja' }` in `useHead()` but the HTML element still shows `lang="en"`.

**Why:** When `automaticDefaults` is enabled (default), the module automatically sets the `lang` attribute based on site config, not from `useHead()` calls.

**Solution:** Set the locale via site config instead:

nuxt.config.ts

```
export default defineNuxtConfig({
  site: {
    defaultLocale: 'ja'
  }
})
```

See the [I18n Guide](https://nuxtseo.com/docs/seo-utils/guides/i18n) for detailed information.

### [Canonical URL Not Using My Custom Logic](#canonical-url-not-using-my-custom-logic)

**Problem:** You're setting a custom canonical URL with `useHead()` but the module overrides it.

**Why:** The module sets canonical URLs with low priority by default when `automaticDefaults` is enabled.

**Solution:** Either disable automatic defaults or use higher priority:

```
// Option 1: Higher priority
useHead({
  link: [{ rel: 'canonical', href: 'https://example.com/custom' }]
}, { tagPriority: 'high' })

// Option 2: Disable automatic defaults
export default defineNuxtConfig({
  seo: {
    automaticDefaults: false
  }
})
```
