# How do I identify the page to customize?

If you can't seem to find the page that you're looking for in [the reference Storybook](https://storybook.keycloakify.dev/?path=/story/introduction--page), first thing to try is to open the developer tool and see the *pageId* of the page you're trying to customize. \\

If you get this error this means that the theme isn't correctly enabled on the client/realm. Checkout [this guide](https://github.com/keycloakify/docs.keycloakify.dev/blob/faq/broken-reference/README.md) or join [our discord server](https://discord.gg/kYFZG7fQmn), we'll help you debug.\

Other scenario you get a page that is not listed in [the reference storybook](https://storybook.keycloakify.dev/?path=/story/introduction--page). This probably mean that you have a third party Keycloak extension enabled on your Keycloak server, you can still customize this page, just follow this guide:
