If your WooCommerce single product page’s CSS is broken, here are some steps to troubleshoot and fix the issue:
1. Clear Cache
If you’re using a caching plugin (WP Rocket, W3 Total Cache, etc.), clear the cache.
Also, clear your browser cache and try reloading the page.
2. Check for Theme Conflicts
Switch to a default WordPress theme like Storefront or Twenty Twenty-Four to see if the issue persists.
If switching fixes it, the problem lies with your theme’s CSS or WooCommerce template overrides.
3. Inspect with Developer Tools
Right-click on the page and select Inspect (Chrome) or Inspect Element (Firefox).
Check if styles are missing or overridden by theme styles.
Look for 404 errors in the console indicating missing CSS files.
4. Force Reload WooCommerce CSS
Add this to your functions.php file to re-enqueue WooCommerce styles:
1 2 3 4 5 6 | function reload_woocommerce_styles() {if (is_product()) {wp_enqueue_style('woocommerce-general');}}add_action('wp_enqueue_scripts', 'reload_woocommerce_styles', 99); |
5. Check for Plugin Conflicts
Disable all plugins except WooCommerce and check if the issue persists.
Re-enable them one by one to find the culprit.
6. Fix WooCommerce Template Overrides
In WooCommerce > Status > Templates, check if any WooCommerce templates are outdated or missing.
If there are outdated templates, update them or temporarily rename the /woocommerce folder in your theme to force WooCommerce defaults.
7. Manually Load WooCommerce Styles
If WooCommerce styles are missing, add this to your theme’s functions.php:
1 2 3 4 5 6 | function add_woocommerce_styles() {wp_enqueue_style('woocommerce-layout');wp_enqueue_style('woocommerce-smallscreen');wp_enqueue_style('woocommerce-general');}add_action('wp_enqueue_scripts', 'add_woocommerce_styles'); |
8. Regenerate CSS (If Using Elementor)
Go to Elementor > Tools > Regenerate CSS and click “Regenerate Files”.
9. Debug Custom CSS
If you’ve added custom CSS, check for errors in Appearance > Customize > Additional CSS.
10. Final Steps
If none of these work, enable WP_DEBUG in wp-config.php:
1 2 3 | define('WP_DEBUG', true);define('WP_DEBUG_LOG', true);define('WP_DEBUG_DISPLAY', false); |
Then check the debug.log file inside /wp-content/.
If you need help, share a link to the page or any errors you see in the browser console.
