Hi, We have been using the opigno system for almost a year for our online learning course. I tried to login as usual this morning 11am (GMT +8) and encountered an error message. "Error The website encountered an unexpected error. Please try again later." I had my technical guy to look at the backend and as far as he can see, no files have changed since he fixed it on the 18th August. He was suspecting that it could be an issue with the database, but he cannot see any errors logged by the DB. Could you help us? Pretty urgent... Many thanks! Augustine.
