WordPress Website from within Facebook page tab (iframe)

Hi all,

I created a fully working voting website with wordpress. There is only one thing. I also load the site within a facebook app (iframe). But apparently the authentication cookies of wordpress don’t work when loading from facebook. I believe this has something to do with 3rd party cookies. I tried to set the P3P header, but that didn’t work out.

Is there a solution/fix for this? I searched the forum, but didn’t find a proper solution..

Thanks a lot

B
