 * I am getting these three errors on installation of the plugin:
 * Notice: Undefined index: _lp_course_author in /home1/sofiah/Test3.physicianfreedom.
   co/wp-content/plugins/learnpress/inc/custom-post-types/course.php on line 265
 * Warning: Cannot modify header information – headers already sent by (output started

   custom-post-types/course.php:265) in /home1/sofiah/Test3.physicianfreedom.co/
   wp-includes/option.php on line 919

   wp-includes/option.php on line 920
 * These only pop up when I click add new course. Is this a problem and how can 
   this be fixed?
