As a website owner, debugging errors on your WordPress site can be frustrating and time-consuming. From broken links to 500 internal server errors, there are many issues that can arise on your website. Fortunately, there are several WordPress debugging techniques that you can use to troubleshoot and resolve these errors. In this guide, we will walk you through the process of debugging your WordPress site and provide you with tips and tricks to help you overcome common issues.
Understanding WordPress Debugging
Debugging is a crucial process in maintaining a healthy and functional WordPress website. Whether you’re a developer, designer, or site owner, you’ll likely encounter issues that require troubleshooting. Common WordPress issues include site crashes, theme and plugin conflicts, broken links, and database errors.
The first step in resolving any WordPress issue is to identify the source of the problem. The error logs contain important information about the issues affecting your website. Error logs can be accessed from the hosting account’s control panel or via an FTP client. Look for files named error_log or debug.log in your website’s root directory or wp-content directory. These logs will provide useful information on errors, warnings, and notices.
If the error logs do not provide sufficient information, you can enable WordPress debugging mode. WordPress debugging mode displays error messages on the front-end of the website, making it easier to identify the source of the problem. To enable debugging mode, add the following code to your website’s wp-config.php file:
define(‘WP_DEBUG’, true);
Once debugging mode is enabled, error messages will be displayed on the site’s front-end. This is helpful in identifying issues related to themes, plugins, or custom code. However, it’s important to disable debugging mode once the issue has been identified and resolved.
Another common WordPress issue is site crashes, which can be caused by a variety of factors, including incompatible plugins or themes, corrupted files, or server issues. To troubleshoot site crashes, start by disabling all plugins and switching to a default WordPress theme. If this resolves the issue, then re-enable plugins and themes one by one to identify the source of the problem.
Broken links are another common issue that can affect your website’s user experience and SEO. Broken links occur when links to pages, posts, or external resources on your website are no longer valid. You can use WordPress plugins like Broken Link Checker to scan your website for broken links and fix them.
Database errors can also cause issues with your website. WordPress stores website data in a MySQL database, and errors can occur due to corruption, incorrect credentials, or server issues. To troubleshoot database errors, start by checking the credentials and permissions for the database user. You can also try repairing the database tables using a tool like phpMyAdmin.
Enabling WordPress Debugging Mode
Before you start debugging your WordPress site, it is important to enable WordPress debugging mode. This mode allows you to view detailed error messages that can help you identify the root cause of the issue. To enable WordPress debugging mode, follow these steps:
- Access your WordPress website’s files through an FTP client or file manager.
- Locate the wp-config.php file in your website’s root directory.
- Open the wp-config.php file in a text editor and add the following code to the file: define(‘WP_DEBUG’, true);
- Save the changes to the wp-config.php file and upload it to your website.
With WordPress debugging mode enabled, any error messages that occur on your website will be displayed on the front-end of your site. This can help you to quickly identify the root cause of the issue.
