Masthead not visible in home page of Portal 7.0
We are having an External Facing Portal. We had Made a change in Masthead and deployed it into the portal Successfully.
When we are previewing the Masthead Iview we are able to see the iview perfectly. When i click on Frameworkpage Preview it is also fine.
But when i try to see the portal from anonymous page Masthead is not getting loaded.
I have checked the Permission or authentication it is set to anonymous.
Can you suggest if restart is needed or any possible way it gets reflected.
Please suggest as this is Production Portal.....in Quality and Development the same par file is working fine and we are able to see from anonymous page.
