Chapter 11: Troubleshooting Common Issues

Even with careful setup and maintenance, you might encounter issues with your WooCommerce store. Knowing how to troubleshoot common problems can save you time and frustration. This section outlines frequently asked questions, common problems, and where to find support.

FAQ and common problems

1. My products are not showing up on the shop page.

• Check Product Status: Ensure your products are published and not set to draft or pending review.
• Visibility Settings: In the product editing screen, under the 'Publish' meta box, check 'Catalog visibility'. Ensure it's set to 'Shop and search results'.
• Shop Page Assignment: Verify that a page is assigned as your shop page in WooCommerce > Settings > Products > General.
• Permalinks: Go to Settings > Permalinks and click 'Save Changes' (even if you haven't made any changes). This can sometimes refresh permalink rules and resolve display issues.

2. My payment gateway isn't working.

• Enable Gateway: Ensure the payment gateway is enabled in WooCommerce > Settings > Payments.
• Correct Credentials: Double-check that you have entered the correct API keys, secret keys, or email addresses for your payment gateway. A single typo can prevent it from working.
• Test Mode: If you're using a test mode, ensure you're using test credentials. If you're live, ensure you're using live credentials.
• Webhooks/IPN: For gateways like Stripe or PayPal, ensure webhooks or IPN (Instant Payment Notification) are correctly configured and pointing to your site. These are crucial for receiving payment confirmations.
• SSL Certificate: Confirm your SSL certificate is active and correctly installed. Payment gateways require a secure connection.
• Plugin Conflicts: Temporarily deactivate other plugins (especially security or caching plugins) to see if they are causing a conflict.

3. Shipping rates are not calculating correctly.

• Shipping Zones: Ensure your customer's address falls within a defined shipping zone. If not, no shipping methods will be available.
• Shipping Methods Enabled: Verify that shipping methods are enabled within the relevant shipping zones.
• Product Dimensions/Weight: Check that your products have accurate weight and dimensions entered, especially if you're using calculated shipping methods.
• Shipping Classes: If using shipping classes, ensure products are assigned to the correct classes and that your shipping methods account for these classes.
• Caching: Clear any caching plugins or server-side caching, as old shipping calculations might be stored.
• Debug Mode: Some shipping plugins offer a debug mode that can provide detailed information on how rates are being calculated.

4. I can't upload images or files.

• File Permissions: This is often a server-side issue related to file permissions on your wp-content/uploads folder. You might need to contact your hosting provider to adjust folder permissions to 755 or 777 (temporarily for testing).
• PHP Memory Limit: Insufficient PHP memory can prevent large file uploads. You can increase it by editing your wp-config.php file or php.ini (contact your host for assistance).
• File Size Limits: Check your WordPress media settings and your host's PHP configuration for maximum upload file size limits.

5. My site is slow.

• Hosting: Poor quality hosting is a common cause of slow websites. Consider upgrading your hosting plan or switching to a specialized WordPress/WooCommerce host.
• Images: Optimize your product images. Use appropriate file formats (JPEG for photos, PNG for graphics), compress them, and resize them to suitable dimensions before uploading. Use an image optimization plugin.
• Caching: Implement a caching plugin (e.g., WP Super Cache, W3 Total Cache, LiteSpeed Cache) to serve static versions of your pages, reducing server load.
• Plugins: Deactivate unnecessary plugins. Too many plugins, or poorly coded plugins, can slow down your site.
• Theme: Use a lightweight, performance-optimized WooCommerce theme.
• Database Optimization: Regularly optimize your WordPress database using a plugin like WP-Optimize.
