Overview of the issue

When using Visual Composer Pro with WPML, you might experience the following fatal error when accessing the Translation Management page:

PHP Fatal error: Uncaught TypeError: Argument 2 passed to WPML\Core\SharedKernel\Component\Post\Application\Query\Dto\PostTypeDto::__construct() must be of the type string, null given, called in ../public_html/wp-content/plugins/sitepress-multilingual-cms/vendor/wpml/wpml/src/Core/SharedKernel/Component/Post/Application/Query/Dto/PostTypeDto.php:26

Workaround

Please make sure you have a full backup of your site before proceeding.

Workaround 1 (Recommended)

Add the following code to your theme’s functions.php file:

add_filter( 'wpml_post_type_dto_filter', function ( $postTypeObject ) {
	if ( is_object( $postTypeObject ) ) {
		$default = $postTypeObject->name ?? '';
		if ( ! isset( $postTypeObject->labels ) || ! is_object( $postTypeObject->labels ) ) {
			$postTypeObject->labels = new stdClass();
		}
		if ( empty( $postTypeObject->name ) ) {
			$postTypeObject->name = $default;
		}

		if ( empty( $postTypeObject->labels->name ) ) {
			$postTypeObject->labels->name = $default;
		}

		if ( empty( $postTypeObject->labels->singular_name ) ) {
			$postTypeObject->labels->singular_name = $default;
		}
	}
	return $postTypeObject;
} );
  

This workaround involves directly modifying plugin code, which can be lost on updates.

• Open: /wp-content/uploads/visualcomposer-assets/addons/themeEditor/themeEditor/PostTypeController.php
• Look for:

  protected function registerPostType()
      {
          register_post_type(  

• And replace it with:

  protected function registerPostType()
       {
  	if (!isset($this->postNamePlural)){
  		$this->postNamePlural = $this->postNameSlug;
       }
     register_post_type(
