When encountering the "Establishing WordPress Database Connection" error, there are several solutions you can try to fix the issue. Here are some steps you can take:

Check database credentials: Verify that the database credentials in your WordPress configuration file (wp-config.php) are correct. Ensure that the database name, username, password, and host are accurate.

Test database connectivity: Confirm that your database server is running and accessible. You can use tools like phpMyAdmin or the command line to connect to the database using the same credentials specified in your wp-config.php file.

Repair database tables: Sometimes, the error occurs due to corrupted database tables. You can repair them by adding the following line of code to your wp-config.php file, just before the line that says "That's all, stop editing! Happy blogging."

Save the file, then visit the following URL in your web browser: http:// your domain. com/wp-admin/maint/ repair. php. This will bring up the WordPress database repair page. Click on the "Repair Database" button to initiate the repair process.phpCopy codedefine('WP_ALLOW_REPAIR', true);
 
1. Check database host:
If you are using a hosting provider, make sure the database host value is correct. Contact your hosting support to confirm the database host information if necessary.

2.Increase memory limit:
Insufficient memory can cause the database connection error. You can try increasing the PHP memory limit by adding the following line to your wp-config.php file, just before the line that says "That's all, stop editing! Happy blogging."
Save the file and check if the error is resolved.
phpCopy codedefine('WP_MEMORY_LIMIT', '256M');
 
3.Restart database server:
Restarting your database server might help resolve temporary connectivity issues. Contact your hosting support or consult the documentation for your specific database server for instructions on restarting it.

4.Check plugins and themes:
Disable all your plugins and switch to a default WordPress theme (e.g., Twenty Twenty-One). Then, check if the error still persists. If it disappears, reactivate your plugins and theme one by one until you identify the culprit causing the database connection error.

5.Contact your hosting provider:
If you have tried all the above steps and the error still persists, it's advisable to reach out to your hosting provider's support team. They can investigate the issue further and provide specific guidance based on your hosting environment.
Remember to always backup your website and database before making any changes to ensure you can revert back if something goes wrong.
