Google DFP safeframe/friendlyframe Issue
<p>Recently ran into some trouble with Google DFP that I'm hoping others have had.</p>

<p>We have a site that's served via SSL and it contains some Google DFP ad tags. Google DFP's debugging console shows no errors in the tags or our implementation of them. (i.e. the tags themselves are fine) </p>

<p>However, the ads are getting served via different methods. Some of the iframes get served as FriendlyFrames and some get served as SafeFrames. The SafeFrame ads appear correctly. The FriendlyFrame ads don't show up.</p>

<p>It appears that the FriendlyFrame ads are running afoul of some sort of browser security measure (likely because the pages are served via SSL).</p>

<p>I looked into this in the DFP docs but haven't found anything that explains how to solve the issue.  There is a setForceSafeFrame method available that I've tried to use but it doesn't actually seem to do anything when I try to use it:</p>

<p>I've setup a test page demonstrating the issue here:</p>

<p><a href="https://methnen.com/ad-test" rel="nofollow">https://methnen.com/ad-test</a></p>

<p>There should be 5 separate ads on the page. If you get all of them refresh the page until you get at least one ad that doesn't show. The broken ads are being served as a FriendlyFrames.</p>

<p>Really hoping someone knows what the heck is going on.</p>
