Good afternoon,
I have several teachers that are getting a Single Sign On Error when trying to log into PowerTeacher. They are active at my school and I have verified that their GlobalID is correct. I have gone into DDE (changing the http 'dde' to 'usm' to modify their record and then changed it back) to 'reset' their record. They have logged out and logged back in, yet still can't get into the system.
