Facebook PHP Api suddenly not working - php

Question

<?php
//get token
$access_token = $facebook->getAccessToken();
$albumCover = $facebook->api("/". $album_id ."?fields=picture", "get");
//echo $albumCover['picture']['data']['url'];
//echo '<pre>';
//print_r($albumCover);
//echo '</pre>';
?>
<div class="fb-album<?php if ($counter % 5 == 0){echo ' no-right';}; ?>">
<a href="<?php the_permalink(); ?>">
<div style="width:160px; height:100px; overflow:hidden;">
<img width="160px" src="<?php echo $albumCover['picture']['data']['url']; ?>" />
</div>
</a>
<p><?php the_title() ?></p>
</div>
All of a sudden this doesnt work, and returns no error, could someone shed some light on this for me?
Thanks
UPDATE:
Found the answer, looks like I could not access the cover photo of each album with ?fields=picture anymore, I had to use ?fields=cover_photo and dig into that array, heres my solution, thanks for all your help STACK
<?php
//get token
$access_token = $facebook->getAccessToken();
$albumCover = $facebook->api("/". $album_id ."?fields=cover_photo", "get");
//echo $albumCover['picture']['data']['url'];
$albumCover2 = $facebook->api("/". $albumCover['cover_photo'] ."?fields=picture", "get");
//echo '<pre>';
//print_r($albumCover2);
//echo '</pre>';
?>
<div class="fb-album<?php if ($counter % 5 == 0){echo ' no-right';}; ?>">
<a href="<?php the_permalink(); ?>">
<div style="width:160px; height:100px; overflow:hidden;">
<img width="160px" src="<?php echo $albumCover2['picture']; ?>" />
</div>
</a>
<p><?php the_title() ?></p>
</div>
I appologize for the formatting, its quite hard to make it look right in this editor

Answer 1

Whenever Facebook API does not get data or does not work,
it logs error in PHP's error log. Check your PHP error log.

Answer 2

There was a breaking changes release today; it's worth checking out the release notes to see how you might have been affected. At a guess, something to do with the privacy changes...

Answer 3

You also need to use setAccessToken method after getAccessToken.
$access_token = $facebook->getAccessToken();
$facebook->setAccessToken($access_token);

Answer 4

As per the error message your have posted in the comment,
If the index active does not exist then you get notice error mod_fcgid. To avoid that you can do check if that index is set / exists.
Code:
if($blah['active']=="something"){foo();}
Should be:
Code:
if(isset($blah['active']) && $blah['active']=="something"){foo();}
