Hi, we have started getting this error continuously:

[09-Jun-2017 15:30:15 UTC] PHP Warning: implode(): Invalid arguments passed in /wp-content/plugins/pixel-de-facebook-para-wocommerce/fb-conf.php on line 109

It’s coming from the following code. Error is in line #109

<script>fbq('track', 'AddToCart', {content_type: 'product', content_ids: [<?php echo (isset($options['product_ref']) && $options['product_ref']) ? implode( ', ',$item) : implode( ', ',$sku); ?>], value: <?php echo $cart_total ?>, currency:'<?php echo $options['currency'];?>'});</script>
