Customers can not access questionnaire!!

I'm writing this message on behave of my friend account  "Skratea@gmail.com"

       After publishing my form for almost 1 month, now the questionnaire my friend created can not access and my customer can not fill the form. I would like to know what's happened to my friend's account and how to fix it?

       Another question, How can I fully access my friend's account?

Thank you in advance

Have you solved this problem already?

I did check your form "Course Registration Form" and did not find any issue with that. I was able to access form without any problem. Please check the screenshot below:

I would suggest you to please test your form again and get back to us if the issue persists.

We will wait for your response.

I solved this problem. I found out that my friend disables the form. that
why it can not be accessed.
Thank you for your quick response

Do get back to us if you have any questions.
