I am running the platform in a native installation. The process “forum” is running properly, and for a single user I cannot view the Discussion page for a course. Message I get on page is “We are sorry, this module is temporarily unavailable …”. Log file /edx/var/log/lms/edx.log contains the following error mesage from python files:
“CommentClientRequestError: [“Username is already taken”]”
As I remember I have deleted this user (probably via Django) and made an account with the same credentials once more.
This is the only user that has this problem with Discussion page. All the rest work properly.
Is there a workaround for this problem? It seems that something was not properly deleted or created for the user.
