Make sure to regularly back up your website to prevent such devastating losses.

4. Use a Child Theme

When working with WordPress, utilizing a child theme is a highly recommended practice.

3. Create a functions.php file inside the child theme folder and customize it according to your specific needs.
4. Activate the child theme in your WordPress dashboard.
5. You can now confidently make modifications to your child theme’s files, such as CSS and template files, without impacting the parent theme.

The concept of child themes was first introduced in WordPress version 2.7. It was developed to provide WordPress users with a secure and efficient way to personalize their website’s appearance and functionality. Since then, child themes have become an essential tool for WordPress developers and users, enabling them to create unique and personalized websites while still benefiting from the updates and improvements made to the parent theme. By utilizing a child theme, website owners can make changes with confidence, knowing that their modifications will not be lost or cause any issues with their website’s functionality.

5. Use a Debugging Plugin

Using a debugging plugin is a helpful approach to troubleshoot WordPress errors. Here are the steps to effectively use a debugging plugin:

1. Choose a reliable debugging plugin from the WordPress repository, such as Query Monitor or Debug Bar.
2. Install and activate the plugin in your WordPress dashboard.
3. Once activated, navigate to the plugin’s settings page.
4. Enable the debugging feature by following the instructions provided by the plugin.
5. Reproduce the error or navigate to the page where the error is occurring.
6. Check the debugging information provided by the plugin, such as PHP errors, warnings, or notices.
7. Analyze the information to identify the root cause of the error.
8. Use the debugging information to make necessary changes, such as fixing code errors or resolving conflicts with plugins or themes.
9. After resolving the issue, disable the debugging feature to prevent unnecessary logging of information.

By following these steps and utilizing a debugging plugin, you can effectively identify and resolve common WordPress errors on your website.
