Answer 1

Please post the code for your logout button, form. However, if it is a form or a link/button, setting target="_top" might do what you're looking for.

Answer 2

You can add target="_top" to your link or you can use javascript to navigate using your top frame:

self.parent.location= "URL TO logout";

Examples:

<a href="logout.php" target="_top">Logout</a>

<a href="javascript://" onclick="self.parent.location='logout.php'">Logout</a>

Other alternative is, into your logged out page, add a javascript code to remove the frames redirecting your document to the top frame:

<script type="text/javascript"> 
    if (self.parent.frames.length != 0){
        self.parent.location=document.location.href;
    }
</script>
