Hi @evatb,
About the error, is it happening few times or every times when you are editing the course in the backend. How can we exactly replicate this issue? We are trying to replicate it but not able to so. Everything seems to be fine when we test.
About the instructor system:
If you want to register instructor in your site, here’s what you need to do.
- Create a new page say ‘Instructor registration’.
- Then add the shortcode [masteriyo_instructor_registration] in that page.
This will create the instructor registration page. More info can be found here in the Masteriyo LMS doc, please check the title Instructor Registration Shortcode.
In the backend, you need to go to Masteriyo -> Users -> Instructors tab. All the users that wanted to register as Instructor will be listed there. You will need to click on them one by one and approve them.
Once the user is registered and approved as instructor they can create the courses on their own by logging in (yoursiteurl/wp-admin/).
Let me know if you have any confusion on this.
Thanks.
