I have been reported by my users that they log in as a student assigned to their course. But when they enter the lessons they do not open, it opens the main page of the website or the header of the course page.
I have tried to attend to their cases and noticed that the problem is in browsers like Edge and Safari, in Chrome it seems to work better.
But I am not clear what it could be.
I attach video.
There must be some problem.
What can I do?
