📝 Title: When do Changes to wp-config.php Take Effect?

📜 Introduction: Are you trying to enable debugging on your WordPress site to fix that pesky plugin issue? 🐞 Look no further! In today's guide, we'll be diving into the world of wp-config.php and uncovering the mysteries of when and how changes take effect. 🕵️‍♀️✨

💡 The Problem: So, you've added the necessary lines to your wp-config.php file as per the WordPress Codex. But, alas, no debug.log file in sight! What gives? 🤔 Does something need to be restarted for these settings to kick in? Don't fret! We've got you covered.

🔍 Exploring the Issue: The wp-config.php file is a crucial component of your WordPress installation, housing vital site configurations. It's no wonder that changes made here have a powerful impact. But when do these changes come to life? Let's break it down:

1⃣ When the File is Read: Changes made to wp-config.php are read whenever a WordPress page is loaded. This means that as soon as a visitor accesses your site, the updated configuration is activated. No need to restart any services or wait for a specific moment. 🎉

2⃣ The Exception: However, there is one exception to this rule. If you have a caching mechanism set up, such as a caching plugin or a server-level cache, it might create a static version of certain pages. In such cases, the changes to wp-config.php may not be immediately visible on those static pages. To rectify this, clear the cache, and voila! The changes take effect across your entire site. 💨

🛠️ Troubleshooting Tips: Now, let's address the issue at hand - the mysteriously missing debug.log file. Here are a few troubleshooting tips to help you out:

✅ Check File Permissions: Ensure that the wp-content folder and the debug.log file have the correct permissions for your web server to write to them. Incorrect permissions can prevent the log file from being created.

✅ Trigger an Error: To test if error logging is functioning correctly, intentionally introduce an error on your site, such as deactivating a plugin or modifying a theme file. If the debug.log file is still nowhere to be found, it means there might be an issue with your configuration or file permissions.

✅ Verify wp-config.php Placement: Double-check that you've made the changes within the correct wp-config.php file in the root directory of your WordPress installation. Making changes to the wrong file won't produce the desired results.

💡 Call-to-Action: And there you have it! 😎 Now you know exactly when changes to wp-config.php take effect and how to troubleshoot common issues like the missing debug.log file. Don't let those plugins play hide and seek with your sanity. Get in there, debug, and make your WordPress site shine! 💪
