Moodle 3.8: globale role "Trainer" adapted - no effect
I have installed the plugin in our Moodle server.
To allow all trainers to install content types themselves, I have changed the global role "trainer" and set the rights for "mod/hvp:installrecommendedh5plibraries" and "mod/hvp:userestrictedlibraries" to allow.
Now when I enroll or register as a trainer in a course, I still don't get the rights.
Where is the error?
