I have created a page in my own developer instance where I have the sys admin access and when I am trying to access the page...I am getting the followng error

Insufficient Privileges


You do not have the level of access necessary to perform the operation you requested. Please contact the owner of the record or your administrator if access is necessary.

I have checked the profile and can see that I have access to the page and corresponding class as well; yet I am having the problem..

Any solution to this will be highly appreciable!!!
