site:previewAsAdmin
This component shows detailed error messages on a site in administrator preview mode. We recommend that you add it right before the closing apex:page tag. Note: The site:previewAsAdmin component contains the apex:messages tag, so if you have that tag elsewhere on your error pages, you will see the error message twice.
Example
The example above renders the following HTML:

| id | String | An identifier that allows the component to be referenced by other components in the page. | 14.0 | global | |
| rendered | Boolean | A Boolean value that specifies whether the component is rendered on the page. If not specified, this value defaults to true. | 14.0 | global |
