conflict with wp_delete_attachment

[fgrs]

since I've been using this plugin I can't get wp_delete_attachment to work, page crashes with following error

Fatal error: Uncaught Error: Call to undefined function is_user_logged_in() in /var/www/[...]/htdocs/wp-content/plugins/dw-question-answer/inc/Permission.php:364 Stack trace: #0 /var/www/[...]/htdocs/wp-includes/class-wp-hook.php(288): DWQA_Permission->restrict_single_question(Array) #1 /var/www/[...]/htdocs/wp-includes/plugin.php(251): WP_Hook->apply_filters(Array, Array) #2 /var/www/[...]/htdocs/wp-includes/class-wp-query.php(3151): apply_filters_ref_array('the_posts', Array) #3 /var/www/[...]/htdocs/wp-includes/class-wp-query.php(3403): WP_Query->get_posts() #4 /var/www/[...]/htdocs/wp-includes/nav-menu.php(972): WP_Query->query(Array) #5 /var/www/[...]/htdocs/wp-includes/nav-menu.php(1011): wp_get_associated_nav_menu_items(1135, 'post_type') #6 /var/www/[...]/htdocs/wp-includes/class-wp-hook.php(286): _wp_delete_post_menu_item(1135) #7 /var/www/[...]/htdocs/wp-includes/class-wp-hook.php(310): W in /var/www/[...]/htdocs/wp-content/plugins/dw-question-answer/inc/Permission.php on line 364
