Hi Antonio,
Lots of testing today because I changed a bit my approach.
I cannot make the wrapper show a page using a custom url corresponding to moodle. The url works ok on standalone in another tab of the browser
I tried:
domain/cours/course/index.php?categoryid=3
cours/course/index.php?categoryid=3
Wrapper set: type=custom URL, then the url. By the way, the Course field is chosing the first in the list but I assume it is not taken into account.
The wrapper works when I chose type "Moodle home"
