The Problem

NextGen Analytics, a tech startup, updated their WordPress theme and immediately lost all mobile functionality. Navigation menus overlapped content, forms were cut off on smaller screens, images broke out of their containers, and the CTA buttons were completely hidden on phones. With 65% of their traffic coming from mobile, conversions dropped by 80% overnight. 47 customer complaints came in within the first 24 hours.

Our Solution

The theme update introduced new CSS Grid layouts that conflicted with the site's custom CSS overrides. We audited all custom styles, resolved specificity conflicts, rewrote media queries to work with the new theme structure, fixed the mobile navigation menu z-index issues, corrected image responsive sizing, and tested across 8 different device viewports including iOS Safari, Android Chrome, and tablet browsers.

The Result

All mobile layout issues were resolved in 73 minutes. Mobile conversions recovered immediately and then increased 285% over the pre-incident rate, because the new theme actually had better mobile UX once the conflicts were resolved. Customer complaints dropped to zero. We documented all custom CSS overrides so future theme updates would not cause similar conflicts.
