On September 22 we discovered that we had a security issue related to one of our plugins (WP Filemanager). We immediately shut down our website and restored to a previous version. Unfortunately, this led to loss of student progress and quiz results. We apologize for the inconvenience and vow to do everything possible to prevent future problems.
Right now, we are requiring all users to reset their password. Please also change your password elsewhere if you’ve used the same one.
