Causes of WooCommerce Cart Problems in WordPress
A malfunctioning WooCommerce cart usually stems from:
- Plugin conflicts (especially with caching or security plugins)
- Caching issues (outdated or improperly cached cart/checkout pages)
- Incorrect page assignments (cart or checkout pages not set correctly in WooCommerce settings)
- Theme incompatibility (custom or outdated themes interfering with WooCommerce)
- Session and cookie blockages (preventing WooCommerce from retaining items in the cart)
- Outdated WooCommerce, WordPress, or PHP versions
- Server configuration issues (insufficient memory, PHP errors)
Understanding these causes will help you target the right solution. Once you’ve identified the likely cause, proceed to the troubleshooting steps below.
How to Fix WooCommerce Cart not Working
Follow these steps in order, starting with the most common and general troubleshooting methods before moving to more technical solutions.
1. Check your WooCommerce Status
- Go to WooCommerce > Settings > Advanced.
- Confirm the Cart and Checkout pages are correctly assigned from the dropdowns.
- If the designated Cart page is missing or assigned incorrectly, cart functionality can break.
Once you have checked your WooCommerce status, the next step is to ensure your software is up to date.
2. Update WooCommerce and WordPress Core to Latest Version
- Regularly update your themes, plugins, and WordPress core to prevent compatibility issues.
- Outdated themes or plugins can cause add-to-cart problems.
Check your WordPress admin frequently and install updates as soon as they are available.
After updating, proceed to verify your WooCommerce shortcodes and page setup.
3. Check WooCommerce Shortcodes
Manually Create Cart Page
If WooCommerce did not create these pages during install, you can manually create a cart page and checkout page.
Verify Shortcode Placement
- Add [ woocommerce_cart ] to the Cart page and [ woocommerce_checkout ] to the Checkout page.
- Ensure the cart page exists as a dedicated page with the correct shortcode. If you suspect broader shortcode issues in your store, you may need to troubleshoot WooCommerce shortcodes not working more generally.
- If the dedicated Cart page is deleted or misconfigured, WordPress may fail to direct customers correctly.

Once your shortcodes and pages are set up, check your permalink settings. |
4. Update Permalink Settings
- Go to Settings > Permalinks in your WordPress dashboard.
- Click Save Changes to refresh the permalink structure.
This can resolve issues where the cart or checkout URLs aren’t resolving correctly, or if the view cart link leads to the wrong page.
After updating permalinks, address any caching issues that may be affecting your cart.
5. Fix Caching Problem
Caching plugins often store outdated versions of the cart, preventing dynamic updates. Choosing fully managed WordPress hosting with proper caching configuration can also reduce these types of issues. Ensure your caching plugin excludes the cart and checkout pages from being cached to maintain dynamic product data.
- Clear your cache (browser, plugin, and server-side).
- Exclude cart and checkout pages from caching in your caching plugin settings.
- Caching plugins can inadvertently save users’ unique cart sessions, causing issues with updates and loading.
Once caching is addressed, check your theme compatibility.
6. Check Theme Compatibility to Fix WooCommerce Cart not Working Error
- Switch to a default WordPress theme (like Twenty Twenty-One) to see if the issue persists.
- If the cart works with the default theme, your current theme may be causing the problem.
If the theme is not the issue, move on to checking plugin compatibility.
7. Check Plugin Compatibility Issues
WooCommerce relies on AJAX to update cart totals without reloading the page. Third-party plugins can interfere with WooCommerce AJAX and stop the cart from updating, which breaks core cart functionality.
- Deactivate all plugins except WooCommerce.
- Test the cart.
- Reactivate plugins one by one to find the conflict.
This helps uncover compatibility issues caused by other plugins or WooCommerce customizations.
If plugin conflicts are not the cause, check your PHP version and server configuration. Persistent technical issues may require expert WordPress support and maintenance services to fully diagnose and resolve them.
8. Update PHP Version to Resolve WooCommerce Cart Not Working Issue
Review WooCommerce Logs
- Review your WooCommerce logs for PHP errors related to cart functionality.
Check Hosting-Level Issues
- If the logs point to a hosting-level issue, contact your provider’s support before changing other settings.
Implement Diagnostic Checks
- Implementing diagnostic checks can help isolate server or PHP issues before you change more settings.
If PHP and server settings are correct, consider increasing your memory limit. A low limit can cause symptoms like a blank WordPress admin panel or other erratic behavior in your dashboard.
9. Increase Memory Limit
Increase Memory Limit via wp-config
Increase Limit using .htaccess
Reliable store communication is also critical; if customers are not receiving order emails, you may need to troubleshoot WooCommerce email notification issues alongside cart problems.
