Yes, in includes/classes/shopping_cart.php see the function is not ended:
if ($products = $pf->loadProduct($products_id, $languages_id)) {
$products_price = $pf->computePrice($this->contents[$products_id]['qty']);
you have to put an } at the end, so the function will look lik this:
if ($products = $pf->loadProduct($products_id, $languages_id)) {
$products_price = $pf->computePrice($this->contents[$products_id]['qty']);
}
