I upgraded my moodle to the latest 1.7 version (from 1.6.x...). Everything was okey, except the Quiz module.
The upgrade process stoped when the system tried to uprgade the quiz module, and tables. Error message: "quiz module needs upgrading". After that, I couldnt do anything inside the portal. Everytime when I login, this message appers, and I cant use my moodle.
I made and used earlier 5 or 6 quizes, and 100 questions. I made of course an sql dump. First I tryed to delete all tables (question and quiz tables) from the database, and so install a complete new quiz module, but I got the same error message. Then I tryed to delete the quiz module from the module list, delete the tables, and the mod/quiz directory, but I got again the error message. I dont know, what else can I do? Advise?
