 * Hello [@vandung93](https://wordpress.org/support/users/vandung93/)
 * It seems maybe something is missing from the Tutor core file or any conflict 
   with another plugin. Please check for the plugin conflict and test the requirements
   meet for the plugin: [https://docs.themeum.com/tutor-lms/troubleshooting/general/](https://docs.themeum.com/tutor-lms/troubleshooting/general/)
 * Let us know if something comes up.
    Thank you
