Question: Today under developer.apple.com member center > iOS Provisioning Portal > Provisioning menu
when clicked only brings up the "Development Provisioning Profiles" 
it has to "Distribution Provisioning Profiles" !
Any idea why this is so? Any change in the way we need to create "Distribution Provisioning Profiles"

Answer: 
I had the Same problem. The Solution was that I was Admin for iOS Development, BUT only a member in Safari Development . Tell your agent to make you Admin for safari too and you will be able see the Distribution Tab.
Only certain users in the portal have permissions to see/use the Distribution Provisioning Profiles tab. I believe "Team Member" roles are not able to see the Distribution tab. Make sure the user you are using to login with is a "Team Agent".
