Sometime yesterday afternoon, all summer courses were made unavailable. We are not sure yet why this happened, but we are still investigating. To correct this, we compiled a list of all courses that were in last spring (132), this summer (133) and next fall (141) that were currently unavailable and have student enrollments. Those courses were made available around 11pm last night. This would have enabled students to access their courses once more. However, if there was an instructor that made their course unavailable and it matched that criteria, it is now available again.
