The “Error establishing database connection” issue in WordPress is a common error that can be caused by a number of different things, but it is usually relatively easy to fix.
- Check your database credentials: Make sure that the database username, password, and hostname entered in your wp-config.php file are correct. You can find this information in your WordPress hosting account control panel.
- Repair your database: WordPress has a built-in database repair tool that can fix minor database corruption. To use the tool, go to the WordPress dashboard and navigate to Tools > Repair Database.
- Check your file permissions: Make sure that the WordPress files and folders have the correct permissions. You can check the file permissions using your FTP client or through your hosting account control panel.
- Disable all plugins: If you have any plugins installed, disable them all and see if that fixes the error. If it does, then you can re-enable your plugins one by one to see which one is causing the problem.
- Increase the PHP memory limit: If you are using a shared hosting plan, your PHP memory limit may be too low.
