WordPress Critical Errors can be frustrating. Often, these errors stem from plugin-related issues. Plugins enhance your site, but they can also cause conflicts. Let’s explore how to handle these issues effectively.

Deactivating All Plugins

First, try deactivating all plugins. This step helps in identifying if a plugin is the issue. You can do this via the WordPress dashboard or through FTP.

  • WordPress Dashboard: Go to Plugins > Installed Plugins. Select all and choose Deactivate.
  • FTP Method: Connect to your site using an FTP client. Navigate to /wp-content/plugins/ and rename the plugins folder to plugins_old.

Once all plugins are deactivated, check if the critical error persists. If the site works fine, a plugin is likely the culprit.

Identifying The Culprit

To find the problematic plugin, reactivate each plugin one by one. After reactivating each plugin, refresh your site to see if the error reappears.

  1. Go to Plugins > Installed Plugins.
  2. Activate the first plugin.
  3. Check your site for errors.
  4. Repeat steps 2-3 until the error occurs.

The plugin causing the error will make your site crash again. Deactivate this plugin and contact its developer for support.

Step Action
1 Deactivate all plugins

3 Reactivate plugins one by one
4 Identify and deactivate the faulty plugin

These steps should help resolve plugin-related issues causing WordPress critical errors.

  • Access your site via FTP or your hosting control panel.
  • Navigate to wp-content/themes/your-theme.
  • Look for files like functions.php and header.php.
  • Rename these files to disable them.

After renaming, check your site. If it works, one of these files is faulty. You can then correct the specific issues within these files.


Core WordPress Files

The core WordPress files are essential for your website. They include critical components that help run your site smoothly. Any issues with these files can cause a WordPress Critical Error. This section will guide you through re-uploading and checking these files.

File Permissions Errors






WordPress Critical Error: File Permissions Errors

Experiencing a WordPress Critical Error can be frustrating. One common cause is file permissions errors. These errors can prevent your website from functioning properly. Learn how to solve these errors by setting correct file permissions.

Setting Correct File Permissions

Correct file permissions are crucial for WordPress. They ensure your files are accessible and secure. Incorrect settings can block access or open security risks.

Follow these steps to set correct permissions:

  1. Access your site’s File Manager or FTP client.
  2. Navigate to the root directory of your WordPress installation.
  3. Locate the wp-content, wp-includes, and wp-admin folders.
  4. Set the permissions for these folders to 755.
  5. Set the permissions for files inside these folders to 644.

Understanding Permission Settings

File permissions define who can read, write, or execute files. They use a numeric system. Here’s a quick guide:

Resolving Syntax Or Parse Errors

Encountering a WordPress Critical Error can be daunting. Syntax or parse errors are common causes. These errors occur due to incorrect PHP code. Fixing them is crucial to restore your website’s functionality.

Identifying Syntax Errors

To identify syntax errors, you need to locate the problematic code. Usually, WordPress displays an error message pointing to the issue. It often includes the file name and line number. This information helps you pinpoint the exact location of the error.

Another method is to enable WP_DEBUG mode. Add the following line to your wp-config.php file:

define( 'WP_DEBUG', true );

This will display detailed error messages on your screen. These messages provide insights into what went wrong.

Editing Problematic Files

Once you identify the error, edit the problematic file. Use an FTP client or your hosting provider’s file manager. Navigate to the file and open it for editing.

Look for the line mentioned in the error message. Correct the syntax mistake by comparing it to proper PHP syntax. For example, ensure all parentheses, brackets, and quotes are correctly placed.

Here’s an example of a common syntax error:

echo "Hello, world!;

The corrected version should be:

echo "Hello, world!";

After making the necessary changes, save the file. Refresh your website to see if the error is resolved.

If the error persists, revisit the error message. Ensure no other syntax issues are present. Sometimes, multiple errors exist in one file.

By carefully identifying and editing problematic files, you can resolve syntax or parse errors effectively. This restores your WordPress site to full functionality.

Connection Timed Out

Experiencing a Connection Timed Out error in WordPress can be frustrating. This error occurs when your website takes too long to respond. It often means your server is overwhelmed. Let’s explore what causes this and how to fix it.

Understanding Timeouts

Timeouts happen when a server takes too long to respond. They can occur due to many reasons:

  • Heavy traffic on your website
  • Limited server resources
  • Slow database queries
  • Improperly coded plugins or themes

Web browsers wait for a response from the server. If the server doesn’t reply within the time limit, a Connection Timed Out error appears.

Extending The Timeout Limit

Extending the timeout limit can help resolve this issue. Here’s a simple method to do this:

  1. Access your WordPress root directory using an FTP client.
  2. Find the wp-config.php file.
  3. Add this line of code to the file: 
    set_time_limit(300);

This code increases the timeout limit to 300 seconds.

Another way to extend the timeout limit is by editing the .htaccess file. Add the following code:



    php_value max_execution_time 300

These changes can help reduce Connection Timed Out errors. Always back up your files before making any changes.

Mixed Content Warning






Fixing WordPress Critical Error: Mixed Content Warning

The Mixed Content Warning happens when your website loads both HTTPS and HTTP resources. This can lead to security risks and can impact user trust. To keep your WordPress site safe, it’s important to fix this issue.

  1. Purchase an SSL certificate from a trusted provider.
  2. Install the SSL certificate on your web server.
  3. Update your WordPress settings to use HTTPS.

After securing your content, you can proceed to fix any mixed content issues.

Mixed content issues occur when some resources are loaded over HTTP. This can include images, scripts, and stylesheets. Follow these steps to fix mixed content issues:

  • Check your website for mixed content using browser developer tools.
  • Update all URLs to use HTTPS in your WordPress dashboard.
  • Use a plugin like Really Simple SSL to automatically fix mixed content.
  • Manually update hardcoded URLs in your theme files and database.

Ensuring all content loads over HTTPS enhances both security and user experience.

Manual updates can be tricky. Make sure you follow each step carefully. This ensures your site runs smoothly.

Cdn And Ssl Troubles






WordPress Critical Error: CDN and SSL Troubles

WordPress critical errors can be frustrating. CDN and SSL issues often cause these errors. Proper configuration is essential to avoid downtime.

Configuring Cdn Settings

A Content Delivery Network (CDN) helps load your site faster. Incorrect settings can lead to errors.

  • Ensure the CDN URL matches your site URL.
  • Check for any cache conflicts.
  • Clear CDN cache regularly.
  • Update CDN settings after major site changes.

Check the CDN provider’s documentation for specific settings. Misconfigurations can lead to critical errors.

Ssl Certificate Renewal

An SSL Certificate secures your site. Expired certificates can cause critical errors.

  1. Regularly check the SSL certificate expiry date.
  2. Renew the certificate before it expires.
  3. Install the renewed certificate promptly.

Most hosting providers offer automatic SSL renewal. Ensure this feature is enabled.
