How to Enable Error Reporting in Magento 2

Do you want to enhance the stability of your Magento store? Knowing how to enable error reporting in Magento 2 helps you detect and resolve errors effortlessly. As developers, it’s crucial to see detailed error messages during extension development or troubleshooting bugs. Often, encountering a blank page in Magento leaves you wondering about the root cause of the issue.

By default, Magento 2 disables error reporting on the front end, making it challenging to identify problems. This guide explains how to enable error reporting effectively and leverage developer mode commands to streamline debugging. With these insights, you can maintain peak store performance and deliver a seamless shopping experience.

A step-by-step guide to Enable Error Reporting in Magento 2

php bin/magento deploy:mode:set developer

if you are still unable to see the error then you just need to edit app/bootstrap.php(from the root of your Magento directory)

Find the code in the above file set as follows:

error_reporting(E_ALL); // Set Error Reporting as E_ALL (Report all PHP errors)

ini_set('display_errors', 1); // Uncomment this line to enable PHP error display

You will see all the errors on the browser now.

Common Issues and How Error Reporting Helps Solve Them

Magento 2, being a robust eCommerce platform, occasionally encounters issues that can disrupt functionality. Here are some common problems developers face and how enabling error reporting helps resolve them:

1. Blank Pages

• Issue: Blank pages, also known as the “White Screen of Death,” occur due to PHP errors in Magento 2, missing files, or misconfigurations.
• How Error Reporting Helps: Enabling error reporting reveals detailed error messages instead of a blank screen, pinpointing the exact file or code snippet causing the issue. This makes debugging Magento 2 errors more efficient and straightforward.

2. Missing Files

• Issue: Missing CSS, JS, or core Magento files can break the frontend or backend functionality, leading to a partial or fully inaccessible site.
• How Error Reporting Helps: Error reporting logs, such as Magento 2 log files, provide a clear path to fix Magento 2 missing files or permissions errors, helping you restore or replace them promptly.

3. Extension Conflicts

• Issue: Installing or updating Magento 2 extensions can lead to compatibility issues, resulting in fatal errors, slow loading, or unexpected behavior.
• How Error Reporting Helps: Error logs display detailed information about conflicting classes, methods, or code blocks, making Magento 2 error reporting for developers an invaluable tool to resolve dependency or override issues.

4. Database Errors

• Issue: Improper database configurations, corrupt tables, or incorrect queries may lead to Magento 2 database connection errors or even site crashes.
• How Error Reporting Helps: By analyzing Magento 2 error logs configuration, you can identify problematic queries, missing tables, or incorrect database connections and fix them efficiently.

5. Theme-Related Issues

• Issue: Custom theme development or third-party theme updates often introduce layout or rendering issues in Magento 2 themes.
• How Error Reporting Helps: Error reporting pinpoints layout XML or missing PHTML file errors, enabling quick fixes to design or structural problems.

6. Server Configuration Problems

• Issue: PHP version mismatches, memory limit issues, or incorrect permissions often cause Magento 2 server errors.
• How Error Reporting Helps: PHP error reporting in Magento 2 provides insights into server-side errors like timeouts, memory exhaustion, or permission issues, enabling timely corrective actions.

7. Cache and Indexing Errors

• Issue: Cache or index-related issues might prevent changes from reflecting or lead to Magento 2 indexing issues.
• How Error Reporting Helps: The error logs highlight the affected caches or indices, helping developers refresh or rebuild them and enable Magento 2 error logs for ongoing monitoring.

8. API or Integration Failures

• Issue: Issues with third-party API integrations, such as payment gateways or shipping modules, may disrupt transactions.
• How Error Reporting Helps: Detailed error messages help trace Magento 2 API integration issues or incorrect configurations, ensuring smooth integration.

To sum up, enabling error reporting in Magento 2 makes debugging easier by providing clear insights into issues. It helps developers resolve common problems quickly and maintain optimal site performance. Regularly enabling error logs ensures a smooth and reliable Magento store.
