    I have directory and event listing CPTs where users are able to edit. It's worked totally fine, and now it's not. When I'm in admin, I'm redirected to the edit form. When I'm in another role, merchant or contributor, which both have editing capabilities, it redirects to the home page. In debug mode I get a php fatal error:

    PHP Fatal Uncaught TypeError: MBFS\Helper::get_post_content(): Argument #1 ($post) must be of type WP_Post, null given, called

    Hello Tanja,

    Thanks for reaching out.

    Does the merchant or contributor user have their own post in the dashboard to edit? I'm not able to reproduce the issue on my demo site. To prevent the fatal error from occurring, you can use the condition code below in the function get_post_content()
    file wp-content/plugins/meta-box-aio/vendor/meta-box/mb-frontend-submission/src/Dashboard/Renderer.php(186)

    
	public static function get_post_content( WP_Post $post ): string {
        if ( ! $post ) {
            return '';
        }
        $content = $post->post_content;

    yes, they have their own post to edit.I'm confused by your solution suggestion and where to put that?
