 * Upon deleting a page I get an error message which refers to the passster plugin.
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, class‘
   passster\PS_Admin’ does not have a method ‘password_lists’ in …/wp-includes/class-

 * The page gets deleted but you have to start WP again.

 * Hey [@ron5](https://wordpress.org/support/users/ron5/),
 * thanks for you message.
 * So this happens when you delete a page which contains a Passster shortcode, right?
   
   I will check that and include a fix in the next support release for that.
 * Thanks!
