We will update the wp Bakery VC plugin,
but since other customers don’t have this issue I think you have some conflict with your installed plugins. Please, deactivate temporarily all plugins you have and check again.
If the theme work, try to activate plugins one by one until the problem occurs again so you will find the problematic plugin.
Can you give us a WordPress admin Username/password, and link to the site in private reply (check a “Set as private reply” checkbox below the post), so we can check directly what’s going on?
