Hi all,
i hope to explain my problem (my english is not good)
Two month ago we have updated our Moodle server from Moodle 2.5 to 3.3.
Everything seemed fine.
After 2 o 3 weeks, one of theachers tells us that all the data generated by plugins "Attendance Register" was
lost (check the "first" attached image, lower part), while all user's session after that date was ok.
We are talking about 3 years of users's sessions.A lot of data.
In this case the only possibility was to take a backup of server before the incriminated date and take
data from database.But how?
Reading php files on "attendantregister" directory, the tables involved SEEMED to be:
dbname_attendanceregister_session
dbname_attendanceregister_aggregate
(the other 2 dbname_attendanceregister and dbname_attendanceregister_lock
had no stats data)
So i've exported with mysqldump all entire data from that two tables and then imported on "new" server.
After that, data was back.
(check the "first" attached image,upper part)
I thought I had solved.
But, if you go in the section "Recalculate Sessions, now" and click on this,
data disappear again. (check the "second" attached image)
I have no idea what to do now.
Any ideas?
Tnks in advance.
