After completing a database attach migration from SharePoint 2007 to SharePoint 2010 I noticed an error occurring on several web pages. The error message was:
Access Denied saving Web Part properties: either the Web Part is embedded directly in the page, or you do not have sufficient permissions to save properties (Web Part ”).
Each page that reported this error had a summary links web part on it. So far the only solution I have found is to view each page using an account with full control permissions for the page / site. To expedite this process I created a small console application I am running after the migration process to automatically test load every page within the farm using a farm administration account.
If anyone comes up with a better solution I would love to hear it.
