My user came back to me in morning and said that he is not able to create a page and was facing "Access Denied" error, i was amazed as the user had full control to the site. So i tried it with my ID and BANG same error. I was not able to make page too havig the same "Full Control" access.
After a complete half day of search and trying different things gladly it worked ,saved my weekend fun.
Solution which i used to get over the error is to add my ID to the "Administrators" group of site and it's all fixed.
Am not sure weather it is something by architecture of other issue but it saved my day.
I got one solution which still needs to be tested :
