Yet again my eyes decided to play with me again ... I deleted the wrong table in the database, I want to delete 'class_app' but instead, I deleted 'class_homework' with just 2 clicks ! Really sorry about that ... it is 6.07 am right now and I know I should to go sleep now. I'm going to ask someone else to read my owls tomorrow ... the last backup of the database is on 20th so no point to restore that ...
