Hmmmm, this is what I thought in a first moment. I double-checked the
log's and couldn't get traces of files being deleted.
What I get are lots of entries like that:
The user with id 'X' viewed the 'page' activity with course module id
Crossing some data from the Web server
makes possible to deduce that a
file was uploaded using the filepicker and also wich file is that.
There's available an older version of this site (a couple of months
ago) just for testing and development, and I'm checking differences in
order to gather some more information.
Those files seemed to be embedded in a page activity and was uploaded
by the same user. Some links was created for users download
and now they broke (in the older version everything goes fine).
I thought that maybe the files were actually in the user private
repository and it thought that wasn't necessary any more, then deleted
I've read a little about Moodle 2.x file management and this kind of
user actions wasn't suppose to break links because there are
references to them elsewhere in the site.
That's because I was looking for more expressive log data.
Thank you very much; I'll be digging a little bit more.
