You click “Update WordPress.” Everything seems fine. Then you try to edit a page. The Divi builder does nothing. No errors. Just silence. WordPress updates sometimes break compatibility. The fix is usually straightforward. Divi Builder Broken After WordPress Update?
The Most Common Culprit: Caching Plugins
After a WordPress update, caching plugins may still serve old versions of Divi files. The builder tries to load them. Nothing works [citation:9].
Fix: Clear all cache. Plugin cache, CDN cache, browser cache, server cache. Then hard refresh (Ctrl+F5).
If you use Hummingbird, WP Rocket, or LiteSpeed, also deactivate them temporarily to test [citation:9].
Second Most Common: Browser Issues
Sometimes the problem is your browser, not your site. Cached JavaScript or extensions can interfere [citation:9].
Fix:
- Clear your browser cache
- Try incognito/private mode
- Try a different browser (Chrome vs Firefox vs Edge)
- Disable browser extensions temporarily
If the builder works in a different browser, your main browser is the issue.
