I recently upgraded our site to Moodle 5.1 and since then the Lambda theme is misbehaving—visual elements are out of place and, more critically, the Dashboard and all course pages refuse to load properly. Other areas render as expected, so I’m convinced the issue sits inside the theme’s templates, CSS, or a stray JavaScript call rather than the core. I’ve ruled out obvious plugin conflicts and cache purges; the problem appears only when Lambda is active. Switching to Boost restores normal operation, which confirms it is a theme-specific fault. What I need now is a developer who knows Moodle theming inside out to: • Inspect the Lambda codebase and pinpoint the display error that keeps those pages from loading. • Apply the fix (PHP, Twig, SCSS, JS—whatever it takes) without breaking the responsive design Lambda is known for. • Test the corrected theme on Moodle 5.1 to be sure the Dashboard and course pages load cleanly across major browsers. Acceptance criteria – Dashboard renders fully with no PHP notices or console errors. – Any course page opens in under three seconds and behaves like it does in Boost. – No visual regressions on mobile or desktop breakpoints. – A concise change log explaining what was fixed so I can maintain the theme moving forward. If you’ve tackled Lambda or similar Bootstrap-based Moodle themes before, this should be straightforward. Let’s get the site looking—and loading—the way it should again.
