I have an issue creating a new Web Site programatically. Sometimes, the following exception occurs: >
Content type ‘0x01010007FF3E057FA8AB4AA42FCB67B453FFC100E214EEE741181F4E9F7ACC43278EE811’ not found in web ‘xxx’
Live Search has no solution (by the way: Google has no solution as well ;-)). The only thing you can do is re-run the SharePoint Products and Configuration Wizard. After that, the error disappears and the site creation process is successful.
The weird thing is, that the content type ID is the ID from the “PageLayout” Content Type… If anyone found another solution I would be very interested.
