Check Database Credentials
To fix the “WordPress Error Establishing a Database Connection Intermittent,” the first step is to verify the database name, username, and password. These credentials are essential for establishing a connection to the database.
To do this, log in to the hosting control panel and locate the wp-config.php file in the root directory of your WordPress installation. Open the file and ensure that the database name, username, and password are correctly specified. Check for any typographical errors or missing characters.
Additionally, you can check the database connectivity using phpMyAdmin, a web-based interface for managing MySQL databases. Log in to phpMyAdmin and ensure that you can connect to the database using the provided credentials.
If the issue persists after verifying the credentials, consider contacting your hosting support for further assistance.
Increase PHP Memory Limit
Sometimes, the “WordPress Error Establishing a Database Connection Intermittent” can be caused by insufficient PHP memory limit. To check the current PHP memory limit, you can refer to the phpinfo file or use a plugin like “WP Memory Usage” to fetch the information directly within your WordPress dashboard.
To modify the PHP memory limit in wp-config.php, open the file and look for the line that says “define(‘WP_MEMORY_LIMIT’, ’64M’);” (the value may vary). Increase the limit by changing the numeric value, for example, to ‘128M’ or ‘256M’.
If modifying the wp-config.php file does not solve the issue, you can try increasing the PHP memory limit in the php.ini file. Locate the php.ini file in your server’s configuration and look for the line that says “memory_limit = 64M” (the value may vary). Increase the limit by changing the numeric value, for example, to ‘128M’ or ‘256M’.
Remember to restart the web server after making any changes to the php.ini file.
Optimizing the database can help improve its performance and potentially resolve the intermittent “WordPress Error Establishing a Database Connection.” Before performing any optimization, it is crucial to back up the database to ensure you have a copy in case something goes wrong.
Several plugins are available in the WordPress repository that can help optimize database tables automatically. Install and activate a reputable plugin like “WP-Optimize” or “WP-Sweep.” These plugins typically offer options to clean up and optimize the database with a few clicks.
If you prefer a manual approach, you can use phpMyAdmin to optimize the database tables individually. Log in to phpMyAdmin, select the appropriate database, and navigate to the “Operations” tab. Look for the “Table Maintenance” section and select the option to optimize the tables.
Remember to proceed cautiously when manually optimizing the database and back up the database before making any changes.
Repair Database Tables
If your database tables become corrupted, it can trigger the “WordPress Error Establishing a Database Connection Intermittent.” Similar to optimization, it is crucial to back up the database before attempting any repairs.
Again, plugins can simplify the process of repairing corrupted database tables. Install and activate a reliable plugin like “WP-DBManager” or “Advanced Database Cleaner” to scan and repair any corrupted tables automatically.
For those who prefer a manual approach, phpMyAdmin provides the option to repair individual database tables. Log in to phpMyAdmin, select the appropriate database, and navigate to the “Operations” tab. Look for the “Table Maintenance” section and select the option to repair the tables.
Remember to proceed with caution when manually repairing database tables and always have a backup.

Check Database Server Performance
Sometimes, the intermittent “WordPress Error Establishing a Database Connection” can be caused by issues with the database server’s performance. It is essential to monitor the server’s CPU and memory usage to identify any potential bottlenecks.
Various monitoring tools are available to track server performance. Ensure that the server is not running at its resource limits, which can impact the database connection. If necessary, adjust the server’s resource limits, such as increasing the memory allocation or CPU priority.
If you are consistently experiencing performance issues, it might be worth considering upgrading to a better hosting plan. A more powerful hosting environment can provide the necessary resources to handle your website’s database demands.
Disable Plugins and Themes
Conflicts within plugins or themes can also contribute to the “WordPress Error Establishing a Database Connection Intermittent.” To identify the possible culprits, it’s recommended to deactivate all plugins and check if the error persists.
Log in to your WordPress dashboard and navigate to the “Plugins” section. Select all the plugins and choose the option to deactivate them. Refresh your website and see if the error message disappears.
If the error resolves after deactivating the plugins, reactivate them one by one and refresh your website after each activation. By doing this, you can identify which specific plugin is causing the conflict.
Similarly, if you are using a custom theme, switch to a default WordPress theme like Twenty Twenty-One to see if the error is theme-related. If the error disappears with the default theme, it indicates that your custom theme might be causing compatibility issues.

Fix Corrupted WordPress Files
corrupted WordPress files can also lead to the “WordPress Error Establishing a Database Connection Intermittent.” To fix this, it’s important to back up the WordPress files before making any changes.
Start by reinstalling the WordPress core files. Download the latest version of WordPress from the official website and replace all the files and directories in your WordPress installation with the fresh copies. This step ensures that all the essential files are intact and not corrupted.
If the error persists, it might indicate specific corrupted files or directories. To identify and fix them, download the WordPress installation files and compare them with your current installation. Replace any files or directories that show discrepancies or signs of corruption.
Remember to be cautious when replacing files and always have a backup of the original files.
Check for DNS and Firewall Issues
DNS misconfigurations or firewall restrictions can also cause intermittent database connection issues in WordPress. To ensure that your DNS settings are correct, contact your hosting provider for assistance. They can verify the DNS records and ensure they point to the correct IP address.
Additionally, temporarily disable the firewall on your server to check if it is blocking the database connection. If the error disappears after disabling the firewall, you might need to adjust the firewall rules to allow the necessary connections.
Furthermore, ensure that proper IP whitelisting is in place for the database access. Check if the IP address used in the wp-config.php file for the database host matches the whitelisted IP addresses configured in your hosting environment.

Contact Hosting Support
After trying the above troubleshooting steps, if the “WordPress Error Establishing a Database Connection Intermittent” still persists, it’s time to contact your hosting support for assistance. Provide them with a detailed description of the issue and the steps you have already taken to troubleshoot.

Implement a Caching Solution
Implementing a caching solution can significantly improve the performance of your WordPress website and potentially mitigate the intermittent database connection error. Caching plugins create static versions of your dynamic web pages, reducing the need for database queries.
Install and configure a reputable caching plugin like “W3 Total Cache” or “WP Super Cache.” These plugins offer various caching options to optimize your website’s performance. Enable database caching specifically to minimize the number of database requests.
For more advanced caching, consider implementing a full-page caching solution like Varnish or Nginx FastCGI cache. These solutions cache entire pages, eliminating the need for database queries altogether.
Remember to monitor your website’s performance after implementing the caching solution to ensure it is effectively reducing database-related issues.
In conclusion, the “WordPress Error Establishing a Database Connection Intermittent” can be frustrating, but with the right troubleshooting steps and patience, it can be resolved. Start by checking the database credentials, increasing the PHP memory limit, and optimizing or repairing the database tables.
