Hi,

do you know how to search for the file in the database?
and why there is no file but the status is submitted 

for this student, I found the following log
The user with id '256 has updated the status of the submission with id '2769' for the assignment with course module id '2758' to the status 'submitted'.

is this normal?
any help appreciated
