WPBakery relies on the active theme to provide the basic page structure, including headers, footers, and content wrappers. When a theme is updated, the new version may change the CSS classes or HTML structure that WPBakery expects, causing page layouts to break. Columns may overlap, margins may disappear, or entire sections may vanish from the page, leaving the website looking completely broken and unprofessional.
This problem can be particularly damaging because it often affects every page on the website simultaneously, and it may not be immediately obvious that the theme update was the cause. The WPBakery editor may still show the correct layout, but the frontend appears broken. Understanding why theme updates break WPBakery layouts is essential for preventing and recovering from this common issue.
The most common cause of this problem is that the new theme version has changed the container CSS classes that WPBakery uses to determine page width and column behavior. Another cause is that the theme has removed or renamed template files that WPBakery relies on for rendering. Caching plugins can also cause the issue to persist even after the underlying problem has been fixed, as they continue serving old versions of the broken CSS.
Why theme updates break WPBakery page layouts
WPBakery uses the theme’s content wrapper classes to determine how wide the page content should be and how columns should behave. If the theme changes its main container class from .container to .wrapper or modifies its grid system, WPBakery’s CSS may no longer apply correctly. The result is columns that do not stack, margins that disappear, or content that spills outside its intended area. The editor preview often uses different CSS, which explains why the layout looks correct in the editor but broken on the frontend.
Another common issue is that the theme update may have removed or renamed template files that WPBakery uses for rendering. WPBakery overrides the default page.php and single.php templates to inject its content. If the theme changes its template structure or uses different template file names, WPBakery may not be able to inject its content correctly, resulting in blank pages or pages missing the WPBakery content entirely. Checking the theme’s changelog for template file changes can help identify this issue.
Caching plugins can cause the broken layout to persist even after the theme update issue has been resolved. The browser, CDN, and plugin caches may all serve old versions of the CSS files that were generated before the theme update. Clearing all caches is an essential step after any theme update to ensure that fresh CSS files are loaded. Additionally, WPBakery may need to regenerate its CSS files to adapt to the new theme structure.
How to check if the theme update broke the WPBakery layout
Temporarily switch to a default WordPress theme like Twenty Twenty-Four and check if the WPBakery layout appears correctly. If the layout works with the default theme but not with the updated theme, the problem is specific to the updated theme. If the layout is also broken with the default theme, the problem is likely with WPBakery itself or with caching. This test helps isolate whether the issue is theme-related or plugin-related.

Custom CSS to restore WPBakery layout after theme update
Add this CSS to the theme’s custom CSS section or to WPBakery’s custom CSS settings to restore basic layout functionality after a theme update. This CSS ensures that the main content area has the expected width and that columns behave correctly. Adjust the selectors based on the theme’s actual container classes, which can be found by inspecting the page source.
.vc_row { margin-left: 0; margin-right: 0; }
.vc_column_container { padding-left: 15px; padding-right: 15px; }
.wpb_wrapper { max-width: 1200px; margin: 0 auto; }

Preventing WPBakery layout problems after theme updates in the future
Always test theme updates on a staging website before applying them to the live production site. Keep a backup of the previous theme version to enable quick rollbacks if problems occur. Document any custom CSS added to make the theme work with WPBakery for easy reapplication after updates. Clear all caches immediately after updating the theme, and regenerate WPBakery CSS from the settings panel.
Consider using a child theme for custom modifications so that changes are not lost when the parent theme is updated. Subscribe to the theme’s changelog to be aware of upcoming changes that might affect WPBakery compatibility. Keep WPBakery updated to the latest version to benefit from compatibility improvements with popular themes, and test all critical pages after every theme update before assuming everything is working correctly.
