<p>I'm working on a client site who is using Umbraco as a CMS. I need to create a custom 404 error page. I've tried doing it in the IIS config but umbraco overrides that. </p>

<p>Does anyone know how to create a custom 404 error page in Umbraco?
Is there a way to create a custom error page for runtime errors?</p>

In
```
/config/umbracoSettings.config
```
modify
```
<error404>1</error404>
```
"
1
" with the id of the page you want to show.
```
```
<errors>
   <error404>1</error404> 
</errors>
```
```
