+## Troubleshooting
+
+### `RollupError` on startup
+
+When running the development server for the first time with `npm run dev`, you might encounter a `RollupError` related to the `nuxt-simple-sitemap` module. This is a known issue that can prevent the application from starting correctly.
+
+To resolve this, you can temporarily disable the `nuxt-simple-sitemap` module.
+
+1. Open the `nuxt.config.ts` file.
+2. In the `modules` array, remove or comment out `'nuxt-simple-sitemap'`.
+3. In the same file, remove the `site` configuration block if it exists.
+4. Restart the development server (`npm run dev`).
