Yesterday i faced a problem related to the page layout. I created a page layout with SummaryLinkFieldControl and its works fine with users having admin permission but for user having less previliges its throwing access denied error.
After searching in the net i came to know that its a problem with summary link web part.
The reason behind this may be safe control entry may not be there in the web config file(Its a just guess)
Its better to have web part zone where we can add summary link web part.
In google try to search with the key
(SummaryLinkFieldControl)
