Issue with my store

Hello everyone !
I’m creating an e-commerce store and I have a problem related to my store. I don’t know why but the presentation of my store has changed (probably after adding the woocommerce plugin). However, when I access the products by category, the store works correctly : https://obligeance.com/categories/nos-collections/joies-et-merveilles/
Could someone help me?
Thanks a lot !
