The CMS features that were rolled into SharePoint have their fair share of issues. Working with one of my recent customers, we found a number of errors in the ULS logs in their farm. The follow errors fit into the two following categories. Although these messages seem scary, they’re just informational in nature.
- If the message starts as “While initializing navigation, found Area placeholder but object was not found at: /SITES/SITECOLLECTION/SUBSITE”, it means that the currently logged in user is not a member of that sub site.
- If the message starts as “While initializing navigation, found Page placeholder but object was not found at: /SITES/SITECOLLECTION/page.aspx”, it means that the page is either in “checked out” state or it’s not a publishing page.
If you don’t want to see these messages anymore, change the logging level for the Publishing category to something higher than Unexpected.
