About This Project
A local business owner contacted me in a panic — their WordPress website was showing ‘Error Establishing a Database Connection’ to all visitors. The site had been down for hours. I investigated the wp-config.php credentials, MySQL user privileges, database server status, and table integrity. The root cause was corrupted database tables combined with a MySQL user that had lost password sync after a server migration. I repaired all corrupted tables, reconfigured the credentials, and brought the site back online — fully functional with zero data loss.

Theme Conflict Issue Fixed
Using Troubleshooting Mode, I switched between default WordPress themes to find out if the issue was theme-related. After confirming the theme conflict, I applied the required fixes and restored the correct theme, bringing the site back to normal.
PHP Version Issue Fixed
I noticed my client’s website was showing a PHP version warning, which can affect security and performance. I upgraded the PHP version from the hosting panel and ensured all plugins/themes were compatible. After updating and clearing cache, the issue was fully resolved and the site is running smoothly again.
Cron Job Issue Resolved
My site’s scheduled tasks were not running properly due to WordPress internal cron issues. I disabled WP-Cron and set up a real server cron job from cPanel to handle tasks more reliably. After switching to the server cron, all scheduled events started working smoothly.
