Troubleshooting Common WooCommerce Cart and Checkout Issues After Updates

24 threads Sep 23, 2025 Plugin → Woocommerce

Content

If you've recently updated WooCommerce and are experiencing strange behavior with your cart, checkout, or product pages, you're not alone. Several users have reported issues where clicking "Add to Cart" redirects to the wrong product, cart items display incorrectly, or country/state dropdowns stop working properly.

Based on community reports, these problems often emerge after WooCommerce core updates and typically stem from conflicts rather than bugs in WooCommerce itself. Here's how to systematically identify and resolve these frustrating issues.

Common Symptoms

  • Clicking "Add to Cart" redirects to a different product than selected
  • Cart displays items from previous sessions or wrong products
  • Country/state dropdowns in cart/checkout become unresponsive
  • Variable products revert to simple products when saved
  • Payment methods disappear from admin settings

Step 1: Conflict Testing (The Most Important Step)

Plugin or theme conflicts are the most common cause of post-update issues. Since these problems don't occur in isolation (Threads 3, 5, 9, 11, 13, 20), a conflict test is essential.

  1. Switch to a Default Theme: Temporarily activate a WooCommerce-compatible theme like Storefront. If the issue resolves, your theme needs compatibility updates.
  2. Deactivate All Plugins Except WooCommerce: If switching themes doesn't help, deactivate all plugins except WooCommerce. Reactivate them one by one, testing after each activation to identify the conflicting plugin.
  3. Check for Caching: Clear all caching layers—plugin cache, server cache, and CDN cache (like Cloudflare). Some users (Thread 18) resolved issues by clearing server-level cache.

Step 2: Check for Known Plugin Incompatibilities

Some plugins may not be fully compatible with the latest WooCommerce version. Pay particular attention to:

  • Payment gateway plugins (Threads 12, 14, 24)
  • Booking and credit system plugins (Thread 8)
  • Page builders like Elementor (Threads 4, 11)
  • Caching and optimization plugins

Visit your plugin developers' support pages to check for compatibility notices or updates.

Step 3: Review WooCommerce Settings

Sometimes updates can reset or change certain settings:

  • Navigate to WooCommerce → Settings → Products and verify your "Add to cart" behavior settings
  • Check WooCommerce → Settings → Advanced to ensure cart, checkout, and my account page endpoints are correctly set
  • Verify that tax settings are properly configured (Thread 17)

Step 4: Test with Default WooCommerce Pages

If you're using custom templates or page builders for cart/checkout pages:

  1. Temporarily switch back to the default WooCommerce cart and checkout pages
  2. Test if the issue persists with the default pages
  3. If the problem resolves, the issue lies with your custom templates or page builder configuration

Step 5: Check for JavaScript Errors

Many cart and checkout issues (Threads 9, 13) are caused by JavaScript errors that prevent proper functionality:

  1. Open your browser's developer tools (F12)
  2. Navigate to the Console tab
  3. Reproduce the issue (e.g., try to add to cart or change country)
  4. Look for any red error messages that might indicate the source of the problem

When to Seek Additional Help

If the above steps don't resolve your issue, consider:

  • Creating a staging site to test more extensively without affecting your live store
  • Checking the WooCommerce status log for errors (WooCommerce → Status → Logs)
  • Enabling WordPress debug mode to capture more detailed error information
  • Providing your full system status report when seeking help from the community

Remember that the WooCommerce team regularly releases updates to address compatibility issues. Keeping your WordPress installation, theme, and all plugins updated is the best long-term strategy for maintaining a smooth-running store.
