Project description:
"I have a Prestashop store that relies on an external product configurator module. Everything works correctly up to the “Add to cart” step, but an error occurs when adding a configured product to the cart. After clicking the button, the cart does not acknowledge the action — there is no confirmation popup, no information about the added product, and the Ajax cart in the header remains empty. At the same time, misleading totals may be displayed, making it appear as if nothing has happened.
For the product to actually appear in the cart, the product page must be manually reloaded. After refreshing the page, the cart shows the correct product with all configured attributes, quantity, and price.
The store is running the standard Prestashop cart module, so the issue appears to lie squarely in the handshake between the configurator’s output and Prestashop’s native cart logic. It is very likely that the problem is caused by a custom theme that interferes with the Ajax event responsible for updating the cart.
Your task is to trace and fix whatever is blocking or scrambling this data transfer. I expect clean, well-commented code changes (override or module patch), a concise note describing what was fixed, and proof that the cart now consistently reflects the correct product, quantity, and price every single time the configurator is used. If a cache clear or a small core tweak is all that’s required, that’s fine — just document it so future updates do not break the fix." (client-provided description)
