yep, it's me from your course. Loving it So many good Moodlers helping out with everyone's doubts. Perfect learning situation
Regarding your suggestion - I must wait a little because my colleague (Raul Fernandez) is trying to install the back up copy that I made from https://learn.moodle.net/pluginfile.php/109073/user/backup/backup-moodle2-course-5388-yl_pron-20150120-1223-nu.mbz?forcedownload=1, https://learn.moodle.net/backup/restorefile.php
Will try out your suggestion too and get back to you.
The sun's really shining now
