There are 2 places where you need to remove instructor from displaying in Courses:

1. Removing the Instructor Information from Single Course / Course Directory

Following are steps to achieve this:

0. Install the WPLMS Customizer plugin.
1. Go to Location : wp admin -> plugins -> editor -> wplms customizer -> customizer_class.php
2. Locate the function : _construct
3. Add the below line in it:

PHP Code:

 

add_filter('wplms_display_course_instructor',array($this,'wplms_display_course_instructor'),1,2);
add_filter('wplms_display_course_instructor_avatar',array($this,'wplms_display_course_instructor_avatar'),1,2);

 

4. Now add the following functions at the bottom of the class:

PHP Code:

 

function wplms_display_course_instructor($instructor_title,$course_id=NULL){
            $instructor_title='';
            return $instructor_title;
        }
        function wplms_display_course_instructor_avatar($instructor_avatar,$course_id=NULL){
            $instructor_avatar='';
            return $instructor_avatar;
        }

 

To show any other information in its place you can simply, add some custom html in $instructor_title and $instructor_avatar.


2. Removing the Instructor information form the Course Thumbnails

add_filter('vibe_thumb_instructor_meta',array($this,'vibe_thumb_instructor_meta'),1,2);

PHP Code:

 

function vibe_thumb_instructor_meta($instructor_meta,$featured_style=NULL){
            $instructor_meta='';

        }
