Introduction
WordPress is a popular content management system used by millions of websites worldwide. However, sometimes users may encounter critical errors that can cause their website to crash or become inaccessible. In this article, we will discuss how to fix a critical error on WordPress and get your website back up and running.
Reinstall WordPress Core Files
WordPress is a popular content management system that powers millions of websites worldwide. However, like any other software, it is not immune to errors and glitches. One of the most common errors that WordPress users encounter is the critical error. This error can be frustrating and can cause your website to crash. Fortunately, there are several ways to fix this error, and one of them is by reinstalling WordPress core files.
Reinstalling WordPress core files is a straightforward process that involves replacing the existing WordPress files with fresh ones. This process can fix any corrupted or missing files that may be causing the critical error. Here’s how to do it:
Step 1: Backup Your Website
Before you start reinstalling WordPress core files, it’s essential to back up your website. This step is crucial because it ensures that you don’t lose any data during the reinstallation process. You can use a backup plugin or your web host’s backup tool to create a backup of your website.
Step 2: Download the Latest Version of WordPress
The next step is to download the latest version of WordPress from the official website. You can download the zip file and save it to your computer.
Step 3: Extract the Zip File
Once you have downloaded the zip file, extract it to a folder on your computer. You can use any file extraction tool like WinZip or 7-Zip to extract the files.
Step 4: Delete the wp-admin and wp-includes Folders
Now, connect to your website using an FTP client like FileZilla. Navigate to the root directory of your website and delete the wp-admin and wp-includes folders. These folders contain the core files of WordPress, and deleting them will remove the corrupted or missing files.
Step 5: Upload the New wp-admin and wp-includes Folders
After deleting the wp-admin and wp-includes folders, upload the new folders that you extracted from the zip file in step 3. Make sure that you upload the folders to the root directory of your website.
Step 6: Upload the Rest of the Files
Now, upload the rest of the files from the extracted zip file to your website’s root directory. You can use an FTP client to upload the files.
Step 7: Update the WordPress Database
The final step is to update the WordPress database. To do this, open your website in a web browser and add /wp-admin/ to the end of the URL. This will take you to the WordPress login page. Log in to your website using your username and password.
Once you are logged in, WordPress will automatically update your database to match the new version of WordPress that you have installed. This process may take a few minutes, depending on the size of your website.
In conclusion, reinstalling WordPress core files is an effective way to fix the critical error on your website. This process is simple and can be done by anyone, even if you don’t have technical skills. However, it’s essential to back up your website before you start the reinstallation process to avoid losing any data. If you are still experiencing the critical error after reinstalling WordPress core files, you may need to seek help from a professional WordPress developer.
Disable All Plugins and Themes
WordPress is a popular content management system that powers millions of websites worldwide. However, like any other software, it is not immune to errors. One of the most common errors that WordPress users encounter is the critical error. This error can be frustrating, especially if you are not familiar with the technical aspects of WordPress. In this article, we will discuss how to fix a critical error on WordPress.
The first step in fixing a critical error on WordPress is to disable all plugins and themes. This is because the error may be caused by a conflict between plugins or themes. Disabling all plugins and themes will help you identify the root cause of the error.
To disable all plugins and themes, you need to access your WordPress site via FTP or cPanel. Once you have accessed your site, navigate to the wp-content folder. Inside the wp-content folder, you will find two folders: plugins and themes. Rename these folders to something else, such as plugins_old and themes_old.
After renaming the plugins and themes folders, try accessing your WordPress site again. If the critical error is gone, then the problem was caused by a plugin or theme. You can now start enabling your plugins and themes one by one until you find the one causing the error.
If the critical error persists even after disabling all plugins and themes, then the problem may be caused by a core WordPress file. In this case, you need to reinstall WordPress. Before reinstalling WordPress, make sure to backup your site to avoid losing any data.
To reinstall WordPress, download the latest version of WordPress from the official website. Extract the downloaded file and delete the wp-config.php file. Upload the remaining files to your WordPress site via FTP or cPanel. Once the upload is complete, access your WordPress site again. If the critical error is gone, then the problem was caused by a corrupted WordPress file.
If none of the above solutions work, then the problem may be caused by a server issue. In this case, you need to contact your web hosting provider for assistance. They will be able to identify and fix any server-related issues that may be causing the critical error.
In conclusion, fixing a critical error on WordPress can be a daunting task, especially if you are not familiar with the technical aspects of WordPress. However, by following the steps outlined in this article, you can easily identify and fix the root cause of the error. Remember to always backup your site before making any changes to avoid losing any data. If you are still unable to fix the critical error, do not hesitate to contact your web hosting provider for assistance.
Increase PHP Memory Limit
WordPress is a popular content management system that powers millions of websites worldwide. However, like any other software, it is not immune to errors. One of the most common errors that WordPress users encounter is the critical error. This error can be frustrating, especially if you are not familiar with the technical aspects of WordPress. In this article, we will discuss how to fix a critical error on WordPress by increasing the PHP memory limit.
Before we dive into the solution, let’s first understand what a critical error is and what causes it. A critical error is an error that prevents WordPress from functioning correctly. It can be caused by various factors, such as incompatible plugins or themes, outdated WordPress version, or insufficient PHP memory limit.
PHP memory limit is the amount of memory allocated to PHP scripts on your server. If your website exceeds this limit, it can cause a critical error. By default, WordPress sets the PHP memory limit to 64MB. However, some plugins and themes require more memory to function correctly. In such cases, you need to increase the PHP memory limit to avoid critical errors.
Now that we know what causes a critical error let’s move on to the solution. Here’s how to increase the PHP memory limit on WordPress:
Step 1: Check the Current PHP Memory Limit
Before you increase the PHP memory limit, you need to check the current limit set on your website. To do this, you can use the WordPress Health Check plugin. Install and activate the plugin, then go to Tools > Site Health > Info. Under the Server section, you will see the PHP memory limit. If the limit is less than 256MB, you need to increase it.
Step 2: Edit the wp-config.php File
To increase the PHP memory limit, you need to edit the wp-config.php file. This file contains essential WordPress settings, including the PHP memory limit. To edit the file, you can use an FTP client or the cPanel File Manager. Once you have access to the file, add the following code at the end of the file:
define( ‘WP_MEMORY_LIMIT’, ‘256M’ );
This code sets the PHP memory limit to 256MB. You can change the value to any number that suits your website’s needs. Save the changes and upload the file back to your server.
Step 3: Test Your Website
After increasing the PHP memory limit, you need to test your website to ensure that the critical error is resolved. If the error persists, you may need to disable plugins or switch to a different theme that is compatible with your website.
In conclusion, a critical error can be a nightmare for WordPress users. However, by increasing the PHP memory limit, you can avoid this error and ensure that your website runs smoothly. Remember to check the current PHP memory limit, edit the wp-config.php file, and test your website after making changes. By following these steps, you can fix a critical error on WordPress and keep your website up and running.
Check for Corrupted Database Tables

One of the most common errors that WordPress users encounter is the critical error. This error can be frustrating, especially if you are not familiar with the technical aspects of WordPress. In this article, we will discuss how to fix a critical error on WordPress.
Check for Corrupted Database Tables
The first step in fixing a critical error on WordPress is to check for corrupted database tables. The database is the backbone of your WordPress website, and any corruption in the database can cause critical errors. To check for corrupted database tables, you need to access your website’s database using phpMyAdmin.
PhpMyAdmin is a web-based tool that allows you to manage your website’s database. To access phpMyAdmin, you need to log in to your website’s cPanel or hosting account. Once you are logged in, look for the phpMyAdmin icon and click on it.
Once you are in phpMyAdmin, select your website’s database from the left-hand side menu. You will see a list of tables in your database. Look for any tables that have the status “in use” or “corrupted.” If you find any corrupted tables, you need to repair them.
To repair a corrupted table, select the table and click on the “Operations” tab. Under the “Table maintenance” section, click on the “Repair table” button. PhpMyAdmin will then attempt to repair the table. Once the repair process is complete, check if the critical error has been resolved.
If the critical error persists, you may need to optimize your database. Over time, your database can become bloated with unnecessary data, which can slow down your website and cause critical errors. To optimize your database, select all the tables in your database and click on the “Operations” tab. Under the “Table maintenance” section, click on the “Optimize table” button. PhpMyAdmin will then optimize your database, which should improve your website’s performance and resolve any critical errors.
Conclusion
Fixing a critical error on WordPress can be a daunting task, especially if you are not familiar with the technical aspects of WordPress. However, by following the steps outlined in this article, you can easily check for corrupted database tables and optimize your database to resolve any critical errors.

Now that we know what a critical error is let’s move on to the solution. The best way to fix a critical error on WordPress is to restore from a backup. A backup is a copy of your website’s files and database that you can use to restore your website to a previous state. If you have a backup, you can easily restore your website to a working state before the critical error occurred.
To restore from a backup, you need to follow these steps:

If you do not have a backup plugin installed, you can check your website’s files and database for backup files. Once you have located your backup files, you can proceed to the next step.
Step 3: Restore your website from the backup
The final step is to restore your website from the backup. To do this, you need to upload your backup files to your website’s files and database.
