# Assign a default error page

Create a default 404 error page for your portal using a system property.

You can assign an error page to a portal using the portal form. If you do not assign an error page using that form, the system uses the default 404 page containing the breakout game widget. Use the default 404 page property \[**glide.service\_portal.default\_404\_page**\] to configure the default error page.

[Create a page](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-user-interface/service-portal/t_ConfigureAPage.md) before adding it as the default error page.

1.  Navigate to **Service Portal** > **Properties**.
2.  In the **Default 404 page for Service Portals**, type the page ID found in the ID field of the page form.
