Check Database Name and Prefix
Confirming that the correct database name is being used is crucial. Make sure that the database name specified in the configuration files matches the actual database name. Additionally, check the table prefix set in the wp-config.php file. Ensure that it matches the table prefix used in the database.

Grant Appropriate Privileges to the User
Sometimes, the database user may not have the correct privileges assigned, leading to the “WordPress Error Establishing a Database Connection.” In such cases, grant the necessary privileges to the database user.

Restore a Previous Clean Backup
If repairing the corrupted database tables does not resolve the “WordPress Error Establishing a Database Connection,” restoring from a previous clean backup might be necessary. Restoring the database to a state where it was previously working can help eliminate any corruption that might be causing the error.

Check WordPress Configuration File
The wp-config.php file contains important settings for connecting to the database. Verify that all the settings in the wp-config.php file are correct. Any errors or typos in this file can result in the “WordPress Error Establishing a Database Connection.” Double-check the file for any mistakes.
Check File for Any Errors or Typos
Errors or typos in the wp-config.php file can cause the “WordPress Error Establishing a Database Connection.” Make sure that there are no syntax errors or missing characters in the file. Carefully review the file to ensure its accuracy. Correct any mistakes found in the file’s contents.
Check Server Resource Limitations
Insufficient server resources can lead to the “WordPress Error Establishing a Database Connection.” Increase the memory limit in the php.ini file to allocate more memory to WordPress. Additionally, adjust the maximum execution time to give WordPress enough time to establish a connection with the database.
Increase Memory Limit in php.ini File
To increase the memory limit, locate the php.ini file on the server. Edit the file and find the “memory_limit” directive. Increase the value assigned to this directive to allocate more memory to WordPress. Save the changes to the file and restart the web server for the new settings to take effect.
Adjust Maximum Execution Time
WordPress may need more time to establish a database connection, especially if the server is under heavy load. Adjusting the maximum execution time setting can accommodate this. Locate the php.ini file and find the “max_execution_time” directive. Increase the value assigned to it to allow WordPress more time to establish the connection.
Check Plugins and Themes
Conflicts with plugins or themes can trigger the “WordPress Error Establishing a Database Connection.” To troubleshoot this, disable all plugins and check if the error persists. If the error disappears, reactivate the plugins one by one to pinpoint the culprit. Similarly, switching to a default WordPress theme can help identify if the issue is theme-related.
Disable All Plugins and Check for the Error
To disable all plugins at once, access the WordPress Dashboard and navigate to the “Plugins” section. Select all plugins and choose the “Deactivate” option from the bulk actions menu. After deactivating the plugins, check if the “WordPress Error Establishing a Database Connection” still occurs. If the error is resolved, proceed with the next step.
Reactivate Plugins One by One to Identify the Culprit
To identify the specific plugin causing the error, reactivate the disabled plugins one by one. After activating each plugin, check if the “WordPress Error Establishing a Database Connection” reappears. If the error occurs upon activating a particular plugin, that plugin may be conflicting with the database connection. Consider updating or replacing the plugin to resolve the conflict.
Switch to a Default WordPress Theme to Isolate Theme-Related Issues
In some cases, the current WordPress theme may be causing the “WordPress Error Establishing a Database Connection.” Switch to a default WordPress theme, such as Twenty Twenty-One, to check if the error persists. If the error no longer occurs with the default theme, the previous theme may have compatibility issues. Contact the theme developer for assistance or consider using a different theme.
Check Web Hosting Provider
If none of the above solutions resolve the “WordPress Error Establishing a Database Connection,” it may be due to issues related to the web hosting provider. Contact the hosting provider’s support team for assistance. They can check if there are any server-related problems or if the server is experiencing downtime that affects the database connection.
Confirm if the Server is Experiencing Downtime
Sometimes, the database connection error may be caused by server downtime. Your hosting provider can confirm if the server is experiencing downtime and investigate any issues affecting the database connection. They can provide valuable insights and assistance in resolving the error.
Check WordPress Core Files
If all other troubleshooting steps fail to fix the “WordPress Error Establishing a Database Connection,” consider reinstalling the WordPress core files. It is possible that some files have become corrupted or missing, causing the error. Reinstalling the WordPress core files can replace any problematic files and restore the proper functionality of WordPress.
Reinstall WordPress Core Files
Start by downloading the latest version of WordPress from the official website. Extract the downloaded file and access your WordPress installation directory on the server. Replace the existing WordPress files with the freshly downloaded ones, excluding the wp-config.php file and the wp-content folder. This process ensures that all core files are up-to-date and eliminates any corrupted files.
Replace Corrupted Files
If only specific files are suspected to be corrupted, it may not be necessary to reinstall the entire WordPress core. Instead, identify the potentially corrupted files and replace them individually. Referencing the official WordPress documentation or seeking guidance from the WordPress community can help determine which files need replacement.
By following these comprehensive steps, you can troubleshoot and fix the “WordPress Error Establishing a Database Connection.” Remember to double-check the database credentials, ensure the server is running, verify the configuration files, check for corrupted files, and seek assistance from your hosting provider if necessary. With patience and attention to detail, you can resolve this common WordPress issue and restore your website’s functionality.
