Cart and Auto Add-to-Cart Issues on My Website

Hello, Tanweer,

Could you please provide temporary wp-admin and FTP access? We will check what can be done to help you.
To grant WP-Admin access, please proceed to create a new user account with an administrator role through your WordPress Dashboard. Once the account is established, you may securely transmit the username and password to us via the Private Content section designated for this purpose.

For FTP access, we require the following details: FTP host, FTP username, FTP password, FTP port, and FTP encryption type. If you need assistance in creating these credentials, please reach out to your hosting provider who will guide you through the process.

Best Regards,
8Theme’s Team

Hello, Tanweer,

Thank you for providing access. We have noticed that you are currently using theme version 9.5.4, while the latest available version is 9.6. Please update the theme or grant us permission to do it for you.

Thank you for updating the theme. We have made some changes, and now the cart will be synchronized across all pages. Please check if the issue has been resolved.

Hello,

Sorry for the delay in our response.

It’s strange that you are experiencing the issue, as everything works fine on our side.

Please provide answers to the following questions:
1. Which browsers and devices were used for testing? Does the issue appear only on mobile or in a specific browser? Please perform various tests.

2. Could you please test if the same issue occurs when using a default theme, such as Storefront (Appearance > Themes)? Let us know the results.

Best Regards,

Hello,

It seems that we have identified the issue on your website; however, this is a rather unique situation that we are unable to reproduce on our test site. Therefore, we will investigate it directly on your website and will inform you as soon as we make any progress in resolving it.

Hello,

We have encountered this issue for the first time and discovered that, for some reason, your cart page is being cached. We have tried disabling all plugins, but the problem does not seem to be related to them. Therefore, we added the following custom code to the child theme to prevent the cart page from being cached.

add_action('template_redirect', function() {
    if (is_cart() || is_checkout() || is_account_page()) {
        // Disable caching headers
        nocache_headers();

        // Disable LiteSpeed Cache (if active)
        if (class_exists('LiteSpeed_Cache_API')) {
            LiteSpeed_Cache_API::disable();
        }

        // Disable WP Super Cache
        if (function_exists('wp_cache_disable')) {
            wp_cache_disable();
        }

        // Disable W3 Total Cache
        if (defined('W3TC')) {
            header('Cache-Control: no-store, no-cache, must-revalidate, max-age=0');
        }

        // Extra safety for reverse proxies / CDNs
        header('Cache-Control: no-store, no-cache, must-revalidate, max-age=0');
        header('Pragma: no-cache');
        header('Expires: Sat, 01 Jan 2000 00:00:00 GMT');
    }
});

However, this solution only partially helps, because when a product is removed from the cart page, the products are completely replaced with others. This is not a template cache issue but rather a database query cache issue. We noticed that you have database optimization plugins installed, and we are concerned that these plugins may have modified the database in such a way that, when a product is removed, the same cart page content is returned.

At this point, the best solution for you would be to restore a database backup created before the optimization was performed using these plugins.
