The problem seems only to occur when accessing dashboard (i. e /wp-admin/*) pages with non admin users. The PostmanAdmin class is loaded and used even for non-admins. However the dependendat PostmanViewController is not! * I made a really quick fix, that works in my usercase there all users are either admin or subscriber. I more robust fix could for sure be made, but sometimes quick’n’dirty is also ok. * In the constructor in PostManAdmin.php I used current_user_can() to prevent PostManViewController from beeing accessed for my subscribers like this: * ``` if ( count( $extensions ) > 0 && current_user_can( 'edit_posts' )) { add_action('admin_menu', [ $this, 'add_menu' ], 20 ); } ``` * instead of this * ``` if ( count( $extensions ) > 0 ) { add_action('admin_menu', [ $this, 'add_menu' ], 20 ); } ``` * A better solution would be not to load PostManAdmin at all for said users, but as I sad: quick’n’dirty 🙂 * [marxhz](https://wordpress.org/support/users/marxhz/) * (@marxhz) * [5 years, 4 months ago](https://wordpress.org/support/topic/fatal-error-uncaught-error-class-postmanviewcontroller-not-found/#post-14011315) * I short sidenote related [@lymf](https://wordpress.org/support/users/lymf/) ‘ s usercase. Since he user with author-roles, my fix will not work. I check if the user have edit-post rights. [@lymf](https://wordpress.org/support/users/lymf/): you have to change ‘edit-posts’ to another right that authors do not have. Or better, make a real fix so I dont have to 🙂 - This reply was modified 5 years, 4 months ago by [marxhz](https://wordpress.org/support/users/marxhz/). * [Tim](https://wordpress.org/support/users/tneville/) * (@tneville) * [5 years, 4 months ago](https://wordpress.org/support/topic/fatal-error-uncaught-error-class-postmanviewcontroller-not-found/#post-14012222) * Hi [@marxhz](https://wordpress.org/support/users/marxhz/), * Thanks for this information!
