Kein Zugriff auf Divi Bibliothek

Hallo zusammen,
mit dem Divi-Theme habe gute Erfahrungen gemacht. Leider erhalte ich die Meldung „Du bist leider nicht berechtigt, Beiträge dieses Inhaltstyps zu bearbeiten.“ wenn ich die Divi Bibliothek aufrufen will als Administrator.
Ich nutze u.a. die Plugins „Admin Menu Editor Pro“ und „User Role Editor“ in den aktuellen Versionen. In beiden kann ich nichts finden was das angeht. Im Divi-Rolleneditor ist auch alles aktiviert.
In der functions.php habe ich „Projekte“ umbenannt:

<?php  

function divi_child_styles() {
wp_deregister_style( 'divi-style');
wp_register_style('divi-style', get_template_directory_uri(). '/style.css');
wp_enqueue_style('divi-style', get_template_directory_uri(). '/style.css');
wp_enqueue_style( 'childtheme-style', get_stylesheet_directory_uri().'/style.css', array('divi-style') );
}
add_action( 'wp_enqueue_scripts', 'divi_child_styles' );

function custom_post_name () {
return array(
'feeds' => true,
'slug' => 'news',
'slug' => 'Tourismus',
'with_front' => false,
);
}
add_filter( 'et_project_posttype_rewrite_args', 'custom_post_name' );

/*Translation for Projects*/ 
add_filter( 'projects_post_type_singular_name', 'replace_project_with_new'); add_filter( 'projects_post_type_plural_name', 'replace_project_with_new'); function replace_project_with_new( $project ){ $replaced = str_ireplace('News', 'News', $project); return $replaced; } 

function new_excerpt_more( $more ) {
	return ' <a class="read-more" href="'. get_permalink( get_the_ID() ) . '">' . __('Read More', 'your-text-domain') . '</a>';
}
add_filter( 'excerpt_more', 'new_excerpt_more' );

Wie kann ich wieder den Zugang erhalten?

Besten Dank!
