Madoo WebdesignParticipantHi Woodmart team,
I hope you’re doing well!
I’m reaching out because we’re experiencing serious compatibility issues with WPBakery Page Builder when running Woodmart on PHP 8.3. As soon as we switch the website to PHP 8.3, the entire site becomes extremely slow and WPBakery fails to load correctly. Switching back to PHP 8.1 immediately fixes the problem, so the issue seems directly related to PHP 8.3 compatibility.
Before we assume anything, could you confirm whether WPBakery + Woodmart is officially compatible with PHP 8.3 at this moment?
To help you investigate, here are the exact error logs we receive when PHP 8.3 is active. All referenced files actually exist on the server, so this seems to be a runtime autoloading/compatibility issue:
Error logs:
1. Missing WPBakery core files (but they are physically present)
CRITICAL Uncaught Error: Failed opening required
‘/wp-content/plugins/js_composer/include/classes/core/class-vc-mapper.php’
(include_path=’.’)
in /js_composer/include/classes/core/class-vc-manager.php:7022. More WPBakery load failures
Failed opening required
‘/wp-content/plugins/js_composer/include/classes/core/presets/class-vc-settings-presets.php’
in /js_composer/include/autoload/hooks/vc-settings-presets.php:273Failed opening required
‘/wp-content/plugins/js_composer/modules/scroll-to-element/module.php’
in /js_composer/include/classes/modules/class-modules-manager.php:3583. WPBakery vendor integration failures
Failed opening required
‘/wp-content/plugins/js_composer/include/classes/vendors/plugins/class-vc-vendor-yoast_seo.php’
in /js_composer/include/autoload/vendors/yoast-seo.php:224. General PHP 8.3 strict issues causing fatal behaviour
We also see runtime PHP strict-mode behaviour that does not occur under PHP 8.1:
Autoload failures
Failing includes
Hard crashes during plugin initialization
WPBakery hooks never completing
Extremely degraded performance (3–5 seconds every admin page)
Again, switching to PHP 8.1 makes the entire site instantly fast and stable, so this appears to be a PHP 8.3 compatibility issue.
Question
Could you please confirm:
Is WPBakery (latest version included with Woodmart 8.3.4) officially compatible with PHP 8.3?
Are these WPBakery include failures known issues under PHP 8.2/8.3?
Is an update or patch expected?
We’d really appreciate your help in diagnosing this. The site is running WooCommerce with Woodmart Child + WPBakery, so stability and compatibility are essential.
Looking forward to your response!

Artem TemosKeymasterHello,
Yes, both our theme and WPBakery are compatible with PHP 8.3 and were tested for a long time. It is used on most of our websites. Please test how it works with the default theme to see if it is somehow related to WoodMart or not.
Kind Regards
