Order broken (no orders since several days)

[jocrea7]

Hello everyone.

(I will pay for a support ticket also but maybe you can help me faster or maybe you can help them too with your clues ?  )

Since several days, when on the front office, when you click on order in the cart, it throws a 500 error.

(we didn't update any module or else since months ago, and i tried disabling the cross-selling display in cart as the cross-selling module is disabled)

 

After having put on the dev mode, i get this error screen (the verbose one is in 5 pictures in the attachments of this topic): 

 

[PrestaShopException]

Invalid product vars

101. if (is_array($product) && isset($product['id_product'])) {

102. $product = new Product($product['id_product'], false, $id_lang, $id_shop);

103. } elseif ((int)$product) {

104. $product = new Product((int)$product, false, $id_lang, $id_shop);

105. } else {

106. throw new PrestaShopException('Invalid product vars');

107. }

108. }

Thank you by advance if you have any clue to help us.
