Hi Dr. Nellie,
I'm afraid I need your help once again. I visited the site to continue working on the course, but the course tabs are not responsive and they do not lead to the relevant section to let me work on it. At the same time an error message is visible as soon as I enter the course.How can this be fixed? You can see the problem in the video I attach.
I'd appreciate your help with this so I can keep working on the course. Thank you in advance.
Warm Regards,
Maria
