Ticket #26516 - "Add to Cart" button frozen (ps_shoppingcart module / Alysum Theme)

Hello Support Team,

I am opening this ticket because I am experiencing a critical issue on my PrestaShop store that is completely blocking sales. The “Add to Cart” button on the product page is not working—it remains frozen and does not trigger any action when clicked.

Hi, Cesar Hermandez.
It seems the issue is fixed → https://mega.nz/file/5B4ExCYQ#1vqBN7WIueveONulurDpxEYwljGLw-_ET0K3xuCQN70.
I reset the cart module in back office.
Please confirm

Thank you for resetting the module; however, the issue is not resolved. The module is still experiencing critical server-side errors that are completely unrelated to local user cache.

Let me explain the technical test I just performed: the cart appeared to be "working" on a secondary browser (Edge) because the browser was retaining old scripts in its local cache. However, immediately after completely clearing cookies, sessions, and browser cache, the module failed again, and the page froze (blurred out) when attempting to add a product to the cart.

I found the bug; it was an incompatibility with the Lite Speed ​​Cache module.

Ok, so the issue is resolved?

There's an incompatibility with the LiteSpeed ​​Cache module. Is there any way to fix it? This is directly affecting the page's performance speed. :(

Honestly, it's very hard to debug. And I don't even sure that's theme's issue. I'll try to figure that out
