Our mdl_context table got corrupted, actually i was moving courses to different Course categories (about 10 courses) once courses moved to category all the courses editing options disappeared and none of the pages have blocks and all the pages are blank.
Cant access any courses just users can log in and logout. I have checked in MDL_CONTEXT table all the fields got same values. the table is not updated properly.
Is there any way to populate the data back.
I have got the database backup of last three months old.
We got 300 courses, 900 users.
Any help would be greatly appreciated
