Solving access denied login for site collection administrators

Recently we migrated the applications from sharepoint 2007 to 2010. Once it’s done, we tried to browse the application but it is giving access denied error. Initially I thought it was due to access issue but I am the primary site collection administrator to that application.

Workaround:  Check status of the content DB whether it is in read-only or not locked stage. If it is in read-only, change it to “Not locked” and then save it.

Now try to browse the application and this time you can able to browse.

Access denied on: Napa tool/ SharePoint 2013 apps

Recently I got the "Access Denied" issue when I try to access the lists data from the Visual Studio 2012 apps and Napa tool.

To get the access permissions from the Napa tool:
You will get the below popup up window once you clicked on "properties" tab[see below fig] and here you can give the access according to your functionality.
