WooCommerce Error Log: A Guide

WooCommerce Error Log: A Comprehensive Guide to Diagnosing and Troubleshooting Issues

Understanding and properly interpreting WooCommerce error logs is crucial for quickly diagnosing and resolving issues that may arise with your online store. This comprehensive guide will teach you how to effectively leverage WooCommerce error logs to pinpoint problems and restore smooth functioning of your store.

WooCommerce Error Logs

WooCommerce, the popular WordPress ecommerce plugin, generates detailed error logs that provide invaluable insight into any problems occurring behind the scenes. Carefully analyzing these WooCommerce error logs enables you to rapidly troubleshoot issues and identify solutions.

There are two main types of error logs in WooCommerce:

  • PHP Error Log: Logs critical PHP errors and exceptions.
  • WooCommerce Log: Logs events, errors and requests specifically related to WooCommerce activity.

These logs can be accessed via cPanel, FTP, or directly through file managers in WordPress. We’ll cover the main locations of these logs later in this guide.

Understanding the messages in these error logs is key to diagnosing WooCommerce issues quickly and accurately.

Understanding Error Log Entries

WooCommerce error logs display detailed reports of the issues occurring on your store, including useful metadata to help trace problems. Here’s an example log entry:

[23-Jan-2023 15:45:23 UTC] PHP Fatal error:  Uncaught Error: Call to undefined function get_plugin_data() in /home/site/public_html/wp-content/plugins/plugin-name/plugin-name.php:3
Stack trace:
#0 /home/site/public_html/wp-includes/plugin.php(524): plugin_name->init()
#1 /home/site/public_html/wp-settings.php(443): do_action('init')
#2 /home/site/public_html/wp-config.php(89): require_once('/home/site/...')
#3 /home/site/public_html/wp-load.php(50): require_once('/home/site/...')
#4 /home/site/public_html/wp-blog-header.php(13): require_once('/home/site/...')
#5 /home/site/public_html/index.php(17): require('/home/site/...')
#6 {main}
  thrown in /home/site/public_html/wp-content/plugins/plugin-name/plugin-name.php on line 3

Let’s break down what each component conveys:

  • [23-Jan-2023 15:45:23 UTC]: Timestamp showing when the error occurred.
  • PHP Fatal Error: The severity level – in this case a critical error.
  • Uncaught Error: Call to undefined function get_plugin_data(): The actual error message describing the issue.
  • Stack trace: Displays the sequence of functions executed leading to the error. Helps trace source.
  • thrown in…on line 3: Identifies exact file location and line number of where error was triggered.

Such detailed error log entries allow you to pinpoint the root causes of WooCommerce errors for troubleshooting.

Common WooCommerce Error Types

WooCommerce logs display different types of error levels and messages. Being able to identify the type of error helps troubleshoot the underlying issue:

Fatal Errors

These are critical errors that stop further execution of the script. WooCommerce functionality will break. Example:

[Fatal Error] Cannot redeclare add_action() (previously declared in /home/site/public_html/wp-includes/plugin.php:79)

Potential Causes: Plugin/theme conflicts, PHP version incompatibility


Warn of non-critical issues that don’t prevent website functioning. But warnings should be addressed.

[Warning] Creating default object from empty value

Potential Causes: Improper variable initialization, database issues


Informational messages that reveal minor code issues. Less urgent but still useful diagnostic data.

[Notice] Undefined variable: add_to_cart_handler

Potential Causes: Variable typos, missing declarations

Catching and addressing these errors when they first appear as warnings or notices prevents escalation to critical errors.

Analyzing Error Logs for Issue Diagnosis

Carefully analyzing the error logs allows you to recognize patterns and trends in the types of errors occurring over time.

Review all entries around a specific timestamp to gain context. Analyze the sequence of specific functions and files executed prior to the error. Trace error origin and propagation this way.

Here are some important trends and insights to identify from systematic error log analysis:

  • Spikes in related error entries indicate a particular new issue arising.
  • Errors consistently traced to the same file location signify an underlying fault.
  • Errors following site modifications (new plugins/themes) suggest compatibility issues.

Dedicated tools can automatically analyze logs and surface insights:

Error Log Explorer

This plugin aggregates and highlights urgent WooCommerce errors for diagnosis. Enables one-click access to raw logs.

WooCommerce Logs

Scans multiple log files and displays graphical trends for easy identification of problematic periods. Filter errors by type/location.

These tools generate actionable error log analytics.

Practical Tips for Troubleshooting WooCommerce Issues

Here are actionable tips for troubleshooting WooCommerce, based on diagnostics from error log analysis:

Follow error guidance: Messages often prescribe specific fixes. Implement them as a first step.

Check compatibility: If errors arose after modifications, revert to previous setup and test.

Consult developer forums: Google error details to find relevant troubleshooting discussions on sites like StackOverflow.

When stuck, seek expert help: WooCommerce developers can perform advanced debugging based on your error logs.

Preventing WooCommerce Errors

While troubleshooting is vital, priority should be on proactively preventing errors through:

  • Regular updates: Update WooCommerce, themes, plugins regularly to avoid version conflicts.
  • Careful customization: Refrain from excessive custom code modifications unless completely necessary.
  • Plugin maintenance: Continuously review and remove unused old plugin installations.

Following WooCommerce best practices goes a long way toward running an optimized online store!
