Where to Find WordPress Error Logs?
Accessing Error Logs via FTP/SFTP
To access WordPress error logs via FTP/SFTP (File Transfer Protocol/Secure File Transfer Protocol), you’ll need to log in to your website’s hosting account. Once logged in, navigate to the root directory of your WordPress installation, which is often named “public_html” or “www”. Within this directory, look for the “wp-content” folder and locate the “debug.log” file. This file contains the WordPress error logs.

Interpreting WordPress Error Logs
Understanding Error Messages
When interpreting WordPress error logs, it’s important to understand the error messages. Error messages typically provide information about the type of error, the file and line number where the error occurred, and any additional details or context. By carefully reading and analyzing these messages, you can gain insights into the underlying cause of the error.
Common Error Codes
WordPress error logs often include error codes that provide a standardized way of identifying and categorizing different types of errors. Some common error codes you may encounter in WordPress error logs include 404 (Page Not Found), 500 (Internal Server Error), and 502 (Bad Gateway). Understanding these error codes can help you diagnose and address specific issues more effectively.
Best Practices for WordPress Error Log Management
Enabling Error Logging
To make the most of WordPress error logs, it’s essential to enable error logging in the first place. By default, error logging is often disabled to prevent potential security risks. However, you can enable error logging by modifying the WordPress configuration file (wp-config.php) and adding a few lines of code. Enabling error logging will ensure that all errors and issues are properly recorded in the logs.
Regularly Reviewing Error Logs
Regularly reviewing WordPress error logs is crucial for staying on top of any issues that may arise on your website. Set aside dedicated time to review the logs and analyze the recurring errors or patterns. By doing so, you can proactively address any issues before they escalate and negatively impact your website’s performance or security.
Taking Action on Critical Errors
Not all errors in the WordPress error logs require immediate attention. However, it’s important to prioritize and take action on critical errors that can significantly impact the functionality or security of your website. These critical errors may include database connection failures, fatal PHP errors, or security-related issues. Addressing these errors promptly can prevent further damage and ensure the smooth operation of your website.
Clearing or Archiving Logs
Over time, WordPress error logs can accumulate a significant amount of data. To prevent the logs from becoming too large and impacting the performance of your website, it’s a good practice to clear or archive old error logs regularly. Clearing the logs removes outdated or irrelevant information, while archiving allows you to keep a backup of the logs for future reference.
