Are you experiencing a frustrating problem with your WooCommerce cart page displaying a “critical error”? Don’t worry, this article will guide you through the steps to identify and fix the issue.
What does it mean when the cart page displays a “critical error” in WooCommerce?
A critical error typically looks like this: “This page contains a critical error. Please check the site’s error logs.”
This means that WooCommerce has encountered a serious problem (usually a PHP error) that prevents the cart from loading properly. The user cannot add products, remove them, or proceed to checkout.
Common causes of a critical error on the WooCommerce cart page:
* Incompatible plugins
* Conflicting themes
* Low memory limit in PHP
* Cache issues
Step 1: Enable debug mode
To start troubleshooting, enable debug mode by adding this code to your wp-config.php file:
“`php
define(‘WP_DEBUG’, true);
“`
This will display error messages on the page.
Step 2: Update all components
Make sure that all plugins and themes are up-to-date. This may resolve the issue.
Step 3: Check plugins and themes
Disable all plugins and re-enable them one by one, testing the cart each time. If an error occurs when a plugin is enabled, it’s likely the cause of the problem.
Step 4: Increase PHP memory limit
Add this code to your wp-config.php file to increase the PHP memory limit:
“`php
define(‘WP_MEMORY_LIMIT’, ‘256M’);
“`
This may resolve low memory issues that are causing the critical error.
Step 5: Clear cache
Clear all caches, including:
* Website caching plugins (e.g., WP Rocket, W3 Total Cache)
* Browser cache
* CDN cache (if using Cloudflare)
Temporary disable cache to test if the issue resolves.
Additional tips:
* Make a backup of your site before making any changes.
* If you’re not comfortable with coding or troubleshooting, consider contacting WooCommerce support or a trusted WordPress developer.
By following these steps, you should be able to identify and fix the critical error on your WooCommerce cart page.
