First of all, excuse me if my English is not good.
Moodle : Moodle 3.3.2+ (Build: 20170915)
The problem is: when I choose to export either in xls, csv, etc. no file is generated or downloaded, instead it shows me on the screen the raw result of the file which I am attaching, in the image for example export to excel and that is the result
Thank you very much for your time and dedication.
a big hug
Marcelita
