"No results found" in HUB creating activity for the first time
in my school we installed the plugin via Moodle, everything seemed fine but when I tried to create an activity for the first time I got this "No results found" in the HUB so I am unable to go on (see pic 1). Tried uploading an example files, and got a lot of "missing library" error messages (see pic 2).
I tried the process as a teacher, but also as the site admin, nothing changed.
I'm stuck at this point. I tried to search the forum but found no solutions. What am I missing?
May thanks and greetings from Italy!
