Missing Site Actions menu in SharePoint 2010 Site Collection

Hi,
I'm among the persons who are members in the Farm Administrators Group. There is only one application which has only one Site Collection. From the CA I added my self as the Secondary site collection administrator but when I open the URL I can't see the Site Actions button.
I think it's still about permission issue but I don't know how to solve it since I have the highest permission (Secondary site admin) on the site collection.
Is there any one can help me?

Regards
