Case Study: WordPress Migration & Security Remediation
The client operated a WordPress website that had been running without major updates for several years. The site was built on WordPress 4.9 with PHP 7.4 — both versions that had long passed their official end-of-life dates and no longer received security patches. The frontend was powered by WPBakery Page Builder, a legacy visual editor that had become increasingly difficult to maintain and was creating friction whenever the client needed to update content.
