Troubles with my cart

Hello everyone,

I’m experiencing troubles with my woocommerce cart :
– I can’t update my cart by adding or deleting a product with + and -.
– Sometimes my cart says it’s empty and when I click on it I can see there’s a produit in it.
– Sometimes it says there’s a product and it’s empty.
– And sometimes it says there’s product A in my cart and when I go to cart it contains product B…

I think the problem might come from my WP super cache plugin but I tried to delete it and it totally broke my website.
Do you have any idea ?

Thanks in advance,

Camille
