Prestshop 1.7.6 Add to cart not working!

[Tirppis]

Hi! I am using prestashop 1.7.6.2 and the "add to cart" is not working or in some cases is working very slow. I don't know if this has anything to do with it, but the translation to that very same button is not working either. I can see the translation at product page, but not at frontpage or when in category. The fornt page "add to cart" isn't working at all and the product page "add to cart" is very very slow.

Can somebody please help me? Where I should go search for a resolution?

Edit: Now the front page is working but it is very slow. I think a customer might think it's broken.

Thank you for your reply. I enabled debug mode. What am I looking for? I don't get any bug at back office when I take products to shopping cart. If I check log messages, I can  see only some translation warnings. In deprecations I get "Enabling the "sensio_framework_extra.router.annotations" configuration is deprecated since version 5.2. Set it to false and use the "Symfony\Component\Routing\Annotation\Route" annotation from Symfony itself." And in debug:

what was the solution?

There was an update at the server and I had to fix some settings there. Then it started to work better, i dont know if it caused the problem but suddenly the problem disappeared.
