I am also facing the same issue.
I have replaced the function se_post_publish_ping in /search-everything/search-everything.php for the function below. This worked for me:
function se_post_publish_ping($post_id) {
//should happen only on first publish
$status = false;
if( !empty( $_POST['post_status'] ) && ( $_POST['post_status'] == 'publish' ) && ( $_POST['original_post_status'] != 'publish' ) ) {
$permalink = get_permalink($post_id);
$zemanta_response = se_api(array(
'method' => 'zemanta.post_published_ping',
'current_url' => $permalink,
'post_url' => $permalink,
'post_rid' => '',
'interface' => 'wordpress-se',
'deployment' => 'search-everything',
'format' => 'json'
));
if (!is_wp_error($zemanta_response)) {
$response = json_decode($zemanta_response['body']);
if (isset($response->status)) {
$status = $response->status;
}
}
}
return $status;
}
