WPC Composite Product does not add to cart

Dear WordPress Support,

I hope this email finds you well. I am writing to seek assistance with an issue I am experiencing on my website, lindi.al.

I have recently installed the WPC Composite Product plugin, and while the majority of its features seem to be functioning as expected, I’ve run into a specific problem. Whenever I try to add a product to the cart using this plugin, the page merely refreshes and the product doesn’t get added to the cart.

I’ve already tried troubleshooting the problem on my end by deactivating other plugins and ensuring that there are no conflicting scripts, but the issue persists.

I would greatly appreciate any guidance or solutions you can offer to resolve this. If you require any further details or logs to assist in the diagnosis, please let me know.

Thank you in advance for your assistance.

Best regards
