Add to cart is not working for unregistered users

Hi @shabbirlone,

I visited the link: https://various.tw/product-category/new-in/ – attempted adding a product to the cart and I see the following error from the browser’s console:

Failed to load resource:the server responded with a status of 502 (Bad Gateway)

Since it’s getting a 502 error on the AJAX call. This could possibly indicate a PHP error is occurring. WooCommerce logs all fatal errors. So you can go to WooCommerce > Status > Logs and then select the fatal error file from the dropdown. This might give you some additional clue as to what code is causing the error. And whether it’s part of your theme or another plugin.

If there are no fatal errors recorded then you could look into setting WordPress in debugging mode and logging errors/warnings to a file. The following documentation explains how this can be done: https://wordpress.org/support/article/debugging-in-wordpress/#example-wp-config-php-for-debugging

If it’s only happening with your custom theme, I would definitely suggest contacting the custom theme developers. Since they would be in a better place to determine which code could be conflicting.

– More about conflict test here: https://docs.woocommerce.com/document/how-to-test-for-conflicts/

I hope this helps,

best.

Thanks for the update @shabbirlone , I’m happy to read you managed to fix it!

With that said, I’m going to mark this as resolved. If you have any further questions, you can start a new thread.

Best!
