stuck at the loading animation

Hello,

Suddenly after the last update the output is stuck at the loading animation. I use the bellow function.

<?php
                    if ( function_exists('wpp_get_mostpopular') ) {
                        /* Get up to the top 5 commented posts from the last 30 days */
                        wpp_get_mostpopular(array(
                            'limit' => 10,
                            'post_type' => 'product',
                            'views' => '0',
                            'range' => 'last30days',
                            'order_by' => 'views'
                        ));
                    }?>
