It’s all about creating a clean and efficient environment to work in.

1. Configuration: Site URL and Home URL

Remember those crucial site URLs? They are the foundation of your website guiding visitors to the right place.

Instead of hardcoding them in the wp-config.php file let’s use the more straightforward method:

Head to your WordPress Admin Dashboard (/wp-admin/).
Navigate to Settings > General.
You’ll find the WordPress Address (URL) and Site Address (URL) fields. Make sure these fields match and start with either http:// or https://.

By keeping these URLs in sync you’ll avoid potential headaches with broken links and unexpected behavior.
