How to Fix Critical Errors in WordPress | Complete Solutions and Steps

WordPress has become the preferred platform for millions of websites. However, just like enjoying a perfect cup of coffee, it occasionally faces ‘critical errors.’ When you try to publish a new post and suddenly encounter the message “there has been a critical error on this website wordpress,” it can feel like a cold splash of water. Fear not! Today, we will delve into how to fix WordPress critical errors and get your website back on track.

Defining Critical Errors and Their Symptoms

What is a critical error? In simple terms, it is a fatal issue that prevents you from using WordPress normally. Common symptoms include:

  • White Screen: The site displays no content, only a blank page.

  • 503 Error: This may lead one to think the server is on a break, but it’s merely experiencing a problem.

  • Database Connection Error: When the website and database are no longer ‘intimate.’

These symptoms indicate it’s time to solve the issue quickly, or even your interest in coffee might fade.

Understanding Debugging Mode: Uncovering the Truth

Debugging mode acts as WordPress’s self-check tool, helping us find the root of the errors. To activate debugging mode, edit the wp-config.php file and add the following code:

define('WP_DEBUG', true);

This opens a window into WordPress, allowing you to see where the problems lie. Remember to change this line back to false after fixing the errors, as debugging mode can expose sensitive information, which we certainly don’t want hackers to access.

Step-by-Step Troubleshooting for Plugin Conflicts

Sometimes, conflicts between plugins can lead to issues. So how can we quickly troubleshoot these conflicts? Here’s the process:

  1. Log in to your WordPress dashboard.

  2. Navigate to the Plugins menu and deactivate each plugin one by one, starting with the most recently installed ones.

  3. After deactivating each plugin, check if the website returns to normal.

If you recently added a new SEO plugin that caused the site to crash, it’s likely the culprit. Stay calm; systematically checking each one will help you find the ‘guilty party.’

Theme Compatibility: How to Quickly Check

If plugins aren’t the issue, it might be time to examine the theme. Did problems arise after a theme update? Try switching to a default WordPress theme (like Twenty Twenty-One):

  1. In the dashboard, click on “Appearance” -> “Themes.”

  2. Activate the default theme and check the website.

If the website functions properly, congratulations! The theme was the ‘bad actor.’ You may consider finding a more compatible theme or updating the existing one.

Database Repair: Emergency Steps to Take

When issues persist, the database is often another potential ‘culprit.’ You can use phpMyAdmin to repair it. Follow these steps:

  1. Log in to your hosting control panel and locate phpMyAdmin.

  2. Select the relevant database and find the wp_options table (the prefix may vary).

  3. Check for damaged entries, such as ‘siteurl.’ If issues are found, click ‘Repair Table’ to attempt database repair.

Make sure to back up your database data before proceeding, just in case.

Server Settings and Error Logs: Hidden Discoverers

Sometimes the issue may stem from server settings. If everything else fails, it’s time to check the error logs. You can access the server via SSH or FTP to view the error_log file. These logs can provide more technical details to guide you to the root cause of the problem.

When All Else Fails: A Guide to Reinstalling WordPress

If you’ve tried all previous methods and still can’t resolve the issue, the last resort is to reinstall the core WordPress files. Ensure that you back up all data and files beforehand. Here’s how:

  1. Download the latest version of WordPress and extract it.

  2. Use FTP to upload the extracted files to your WordPress directory, overwriting the existing files (be careful not to overwrite the wp-content folder and wp-config.php file).

  3. Refresh the website and check if it returns to normal.

If all goes well, congratulations! You’ve successfully navigated technical obstacles and emerged as a WordPress hero!
