During January 2026, Flanges Slash0t focused on backend development for the TryGhost/Ghost repository, addressing a critical caching issue in the Ghost Admin interface. Using Express.js and JavaScript, Flanges identified and resolved a problem where the Last-Modified HTTP header caused browsers to serve stale admin HTML, leading to outdated CSS and JavaScript assets. By preventing Express from adding this header to admin responses, Flanges ensured that the admin UI always loads the latest assets without requiring hard refreshes. This targeted bug fix improved admin reliability, reduced cache-related support tickets, and contributed to a more maintainable caching strategy for Ghost Admin.
