Eshop crashed

Hello,

From one day to another our eshop crashed. If I click on any category with products on the main menu it shows a non-working blank page. Even the carrousels with products are blank. When I look in the backend in products, I can see in the dashboard 350 products, but when I click to see them it shows a blank products page (this happens with categories, manufacturers, etc).
I tried to update the extension but apparently there aren't updates.

Do anybody knows what could have gone wrong?
