+themes/AdminLTE/layout.html - Primary fix: moved %body% placeholderthemes/AdminLTE/topbody.html - Simplified to prevent conflictsthemes/AdminLTE/botbody.html - Simplified to prevent conflictsThe core issue was that AdminLTE's layout.html had the %body% placeholder inside a <ul class="nav nav-sidebar"> element, which is designed for navigation menu items, not general page content. When login success messages or other page content was rendered, it created invalid HTML and broke the layout.
The fix moves the %body% placeholder to AdminLTE's designated content area using proper AdminLTE CSS classes and structure, ensuring all page content renders correctly while maintaining the theme's visual design.
Users experienced white screens when logging in with certain themes (particularly AdminLTE). The issue was caused by incorrect HTML structure where page content was being rendered inside navigation sidebars instead of main content areas.
