# Can't 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 devlopper tool and see the page id of the page you're trying to customize.  <br>

If you get this error this means that the theme isn't correctly enabled on the client/realm. Checkout [this guide](https://doc-old.keycloakify.dev/documentation/v11/enabling-your-theme) 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 extention enabled on your Keycloak server, you can still customize this page, just follow this guide: &#x20;
