Gallery was working fine & now there's an error - no idea why plz help

Hello, I've used powergallery in a clients site. Been working fine during the build of the site & for the past week since we went live. Now we're getting an error. Nothing has been changed to any of the files for the gallery or anything like that.

"Warning: Invalid argument supplied for foreach() in /home/USR/public_html/gallery/galleries/global.php on line 55" error in every gallery.

Why is it doing this / what happened? I can't figure it out. Please help ASAP. The site & one of the galleries can be viewed at: [url]

I replaced the global.php file with the one from the PowerGallery update & now the error is gone. I would still like to know what happened & why the gallery just stopped working & that error came up. Nothing was changed. Is there a bug in this software? Here's a copy of the entire global.php that had the error. Please advise.

require_once(realpath($abs_prefix . '../') . '/Connections/powergallery.php');

$GLOBALS['wa_settings'] = array();
$result = mysql_query('SELECT * FROM wa_settings');
while($row = mysql_fetch_assoc($result)) {
$GLOBALS['wa_settings'][$row['name']] = $row['value'];


$pg_config = array(
'path' => $GLOBALS['wa_settings']['pg_root'],
'html_prefix' => $GLOBALS['wa_settings']['pg_root'] . substr($abs_file, strpos($abs_file, '/galleries/') + 1) . '/'


if(!function_exists('get_gallery')) {
function get_gallery($url) {
global $abs_prefix, $pg_config;
$gallery = array(
'title' => '',
'images' => array()

//load using url (requires fopen wrapper support)
$sxe = @simplexml_load_file($url);

//failed (likely due to no fopen wrapper support)
//try loading via include file and XML string
if(!$sxe) {
$connections_prefix = realpath($abs_prefix . '../') + '/';
$args = substr($url, strpos($url, '?') + 1);
$args_array = explode('&', $args);
foreach($args_array as $arg) {
$arg_array = explode('=', $arg);
$_GET[$arg_array[0]] = $arg_array[1];
$_SERVER['PHP_SELF'] = $pg_config['path'] . 'fakey.php';
$no_xml_header = true;
include(realpath($abs_prefix . '../mediarss.php'));
$sxe = simplexml_load_string(ob_get_contents());

if($sxe) {
//gallery info
$gallery['title'] = $sxe->channel->title;

$images = array();
foreach($sxe->channel->item as $item) {
$media = $item->children('');
$thumbnail = $media->thumbnail->attributes();
$full = $media->content->attributes();
$supersize = $media->supersize ? $media->supersize->attributes() : false;
$images[] = array(
'title' => htmlspecialchars(strval($media->title)),
'description' => htmlspecialchars(strval($media->description)),
'thumb' => array('url' => strval($thumbnail['url']), 'width' => strval($thumbnail['width']), 'height' => strval($thumbnail['height'])),
'fullsize' => array('url' => strval($full['url']), 'width' => strval($full['width']), 'height' => strval($full['height'])),
'supersize' => empty($supersize) ? array() : array('url' => strval($supersize['url']), 'width' => strval($supersize['width']), 'height' => strval($supersize['height']))
$gallery['images'] = $images;

return $gallery;

if(!function_exists('get_mediarss_url')) {
function get_mediarss_url($args) {
return $GLOBALS['wa_settings']['pg_rooturl'] . 'mediarss.php?' . $args;

impossible to say what the problem was to be honest. I don't see any difference in the global.php code you posted and the one I have.

My only guess is that the PHP server had a hiccup.
