The Client
Ultimate Blocks is a free WordPress plugin offering 25+ custom Gutenberg blocks designed for bloggers, content marketers, and affiliate publishers.

The plugin has 50,000+ active installs and over 726 reviews on WordPress.org with a 4.9/5 rating.
The Brief
With 50,000+ active installs and a user base spanning high-traffic affiliate and content sites, any bug in Ultimate Blocks has an outsized real-world impact. The plugin needed ongoing reliability work to stay compatible with WordPress core updates and handle edge cases surfaced by its diverse user base.
What Shipped
Contributed PHP and JavaScript fixes targeting block registration, save/edit parity issues, and deprecation handling across multiple blocks. Work focused on maintaining backward compatibility so existing content rendered correctly after plugin or WordPress core updates.
How it was built
Each block is registered as a standalone WordPress block with a PHP server-side component and a React-based editor UI. Block save functions must be kept in strict parity with historical versions to avoid block validation errors on existing content — a constraint that shapes every change.
Gutenberg's strict save-function immutability means any output change requires a formal deprecation entry. Getting this right across a multi-year plugin history without breaking existing posts required careful forensic work on prior block versions.
Results & reach
Contributions improved stability across several blocks for a plugin with 50,000+ active installs, 726 reviews, and a 4.9/5 rating on WordPress.org — reducing error reports and keeping the plugin compatible with current WordPress versions.
