# Edit a WordPress site’s Nginx configuration

Change the web server rules for a WordPress site, for example to add a redirect. Nuvlo checks your changes and rolls back anything invalid.

## Before you start

- The owner or admin role in the account.
- Some knowledge of Nginx configuration.

## Step 1: Open the editor

Open the site, click **Settings** and scroll to **Nginx configuration**. Click **Edit configuration**. The site’s current configuration loads into the editor.

## Step 2: Make your change

Edit the text. To start over, click **Discard changes**, which loads the current file again.

## Step 3: Save and reload

Click **Save and reload Nginx**. Nuvlo tests the configuration before using it.

If Nginx rejects it, you see **Nginx rejected the config. The previous config was restored.** with the error, and nothing changes for visitors.

A valid configuration can still break the site, for example with a wrong redirect, so open the site right after saving.

## Good to know

- The configuration can be up to 100 KB.
- API tokens can’t change it. Sign in to the dashboard instead.
- For firewall rules, bot blocking and the sign-in page, use the **Protection** card instead. See [Protect a WordPress site](https://app.nuvlo.dev/docs/wordpress-security).
