Your WordPress site breaks after a theme update. Here’s why it happens—and what to check first.
Symptom: Broken layouts, missing menus, or 404 errors after updating a theme. Likely cause: Incompatible plugins, outdated theme files, or corrupted update packages. What to check first: Review active plugins for conflicts (disable them one by one), verify the theme’s version matches the WordPress core, and ensure your site’s files weren’t modified manually before the update.
Theme updates don’t have to break your site. But when they do, the fix starts with methodical troubleshooting. Need help diagnosing or fixing a broken WordPress site? Start here.
