# Configure and customize the 404 error page

Source: https://www.goodbarber.com/help/organize-your-content-r93/configure-and-customize-the-404-error-page-a291/

When**a page is not found** in your native or Progressive Web App (PWA), our servers will send an error called error 404. This can happen when the content has been removed or moved or when the URL is typed incorrectly. The page sent by the servers to indicate the presence of this error is a generic page called **404 page**.

To customize this page:
1. Go to bottom left menu **Settings > App Settings > 404 error** in your back office.
2. Fill in the text that will be displayed.
3. Edit the font, colors.
4. Optional: Add an **image** (1024 x 1024 px) by selecting "**Image**" in the title instead of "**Generic Text**".
5. Update your modifications in the menu **Publish > PWA > Update**to apply the changes.

***Note:** Menus have changed in the back office, but the behavior explained in the video is still accurate.*
