# Error Codes and Quick Fixes

We are here to help solve those pesky error messages!

## Error 2001

This error message means that you don't have access to the page.

For example, if an Event’s **Visibility Control** field excludes a type of Attendee and that Attendee type goes to the Event's webpage, they will not see the Registration page. Instead, they will get the Error 2001.

To allow them to see the Registration page, remove the value(s) from the **Visibility Control** field, click **Save**, and click **Update** on the Event.

Error 2001 can also occur when selected [Visibility Controls](https://docs.blackthorn.io/docs/visibility-control) on the Attendee, Contact (for Experience Cloud only), Event Item, and Session records exclude a type of Attendee.
