wp-admin doesn't work inside frames anymore

You have to edit the file wp-login.php putting in a p3p license. 5 years ago it was in line 9, now in WordPress 3.3.1 it is in line 43.

I had the same problem as you, I tried this solution with WordPress 3.3.1 recently, and it worked, I could access to the login page, and admin panel, using frameset.

Here is the solution:

Your original code should be something like this:

function login_header($title = 'Log In', $message = '', $wp_error = '') {
	global $error, $is_iphone, $interim_login, $current_site;

	// Don't index any of these forms
	add_action( 'login_head', 'wp_no_robots' );

You will have to include the following code there:

header( "P3P: CP=CAO DSP COR CURa ADMa DEVa OUR IND PHY ONL UNI COM NAV INT DEM PRE");

It should be right before the part that says “//Don’t index any of these forms” -the line 43-. So your final code will be something like this:

function login_header($title = 'Log In', $message = '', $wp_error = '') {
	global $error, $is_iphone, $interim_login, $current_site;
header( "P3P: CP=CAO DSP COR CURa ADMa DEVa OUR IND PHY ONL UNI COM NAV INT DEM PRE");
	// Don't index any of these forms
	add_action( 'login_head', 'wp_no_robots' );

I hope it work. I have not found any problem yet. If you find any problem, please tell us.

I tried pasting this code into my wp blog but the wp-admin is still not showing up in iframe in any browser. It just comes up as a white screen. I am trying to embed my whole wp site in a facebook iframe for a facebook app and all pages load fine in the iframe except the wp-admin pages are blank when I go to them in the facebook app. any ideas here?

Ok, I found a solution for my problem.
You have to do it after each upgrade again – but it works for me:

1) open wp-includes/default-filters.php
2) find “frame”
3) you’ll get two lines:

add_action( ‘login_init’, ‘send_frame_options_header’, 10, 0 );
add_action( ‘admin_init’, ‘send_frame_options_header’, 10, 0 );

4) comment those lines out, upload the file again and it will work, after the cache has been refreshed.

you are awesome! ive been looking for so long for a solution and this works!! thanks!

I’m sorry that I forgot to post my solution here. Actually, I found it several days after I made this post… :-/

So I hope that this solution will help more users with the same problem!

I am using version 3.4 and when I go to wp-includes/default-filters.php to look for “frame” it does not exist on there. It’s not listed. It does state on top that “Not all of the default hooks are found in default-filters.php” so if this is true, where would I find “frames” to be able to fix this issue?

AWESOME!

You are the MAN,… Thank Bro this ‘things’ is realy realy precious to all.

BUT what about risk? Is this a safe way to ride on?

@aaronmorales: I have not updated, yet, so I don’t know, sorry.

@moziq: As far as I read it’s only a weird kind of fraud protection, but honestly I have no idea. I use this workaround for about 9 month now on a big project and I have not recognized any problems, yet.

My issue has already been resolved here but thank you.
