Fix WordPress Database & PHP

My WordPress site https://www.quicketch.com has gone offline with the message “Error establishing a database connection.” The first order of business is updating PHP to the latest version supported by Hostinger; once PHP is current I expect the database connection issue to be resolved or, if it persists, to be troubleshot and repaired right away.

After the site is back online, the built-in payment gateway also needs attention so that new orders can be processed again without errors. The site runs on a typical Hostinger stack (cPanel/MySQL, no custom framework), so you should be comfortable working inside that environment, checking wp-config.php, repairing tables via phpMyAdmin, and tweaking .htaccess or plugins if version compatibility requires it.

Deliverables
• Site loads normally without the database error
• PHP upgraded to the newest stable release available on Hostinger
• Payment gateway tested end-to-end and confirmed operational

Please keep downtime to a minimum; I will provide full panel and WordPress admin access as soon as we agree on the task.
