Hi,
We're getting the following error when viewing the page template in Site Manager in design view. However, the page displays in CMS Desk with no issue and displays in the browser with no issue. A custom control was added to the page template (not the master template). Any ideas?
[Exception: There was an error processing the page. The error can be caused by the configuration of some component on the master page. Check the master page configuration or see event log for more details. Original message: Object reference not set to an instance of an object.]
