WPBakery Page Builder Version 6.9.0 is running on a theme but Version 6.10.0 running on the WPBakery Page Builder website. so I need to update the file of all plugins.
Please go to Appearance >> Install Plugins >> Update the WP Bakery plugin. If still you will not able to update the plugin then please share the WP admin login details so I will update the plugin for you.
If you aren’t able to update the WPBakery plugin from Dashboard > Appearance > Install Plugins then please share your Site WP-ADMIN Login details in the Private Content field so that we can check this concern on your Site and help you out accordingly.
