The project has been set up as multisite.

If I am trying to get the contents by https://111.com/civicrm/?page=CiviCRM&q=civicrm%2Fevent%2Finfo&reset=1&id=1. Everything works well.

But if I change it to https://222.com/civicrm/page=CiviCRM&q=civicrm%2Fevent%2Finfo&reset=1&id=1. It just shows [Do not delete this page. Page content is generated by CiviCRM.]

Can any one help me out?
