Product page load times over 5 minutes/PHP error, connection time out

So i was wondering why the product pages on my Woocommerce webshop load takes almost 5 minutes … i’ve found out with debugging mode in wp-config.php that’s it’s trying to fetch something and after a few minutes the connection times out. But i’m not sure what’s going on here. I think this function has something to do with the Facebook API? Could someone please help me out?

The error i got is as follows: file_get_contents(https://graph.facebook.com/https://www.filmoutlet.nl/product/spiderman-1-en-2-4-disc-complete-collection-boxset) [function.file-get-contents]: failed to open stream: Connection timed out in /home/mennoep141/domains/filmoutlet.nl/public_html/wp-content/plugins/simple-share-buttons-adder/simple-share-buttons-adder.php on line 941

And on line 941 it says: $htmlFacebookShareDetails = file_get_contents(‘https://graph.facebook.com/’ . $urlCurrentPage);
