Community Q&A

How do I fix WooCommerce product pages returning 404 errors?

Navigate to Settings > Permalinks, click Save Changes to flush rewrite rules, or check for conflicts with caching plugins like LiteSpeed.

What is the best way to identify a plugin conflict?

Enable WP_DEBUG in your wp-config.php file to see specific error logs, or use a staging site to deactivate plugins systematically.

Why is the Gutenberg editor showing a white screen for products?

This is often caused by a JavaScript conflict between plugins or an outdated theme; check the browser console for specific script errors.

Should I disable all plugins to find a conflict?

While common, it is inefficient; using WP_DEBUG or a binary search method (disabling half at a time) is faster for identifying the culprit.
