[Solved] hyperlinks to activity not working

Hi all. I have put Joomdle courses module on and by navigating from there I reach course content. It displays the list of lessons reasonably well, but there is no hyperlink from a list of activities to the activity itself. In other words, I see an activity in the list of activities, but if I try to click on an activity, nothing happens, I expected that to be possible. Am I missing something, or there is no such functionality in joomdle?
Joomdle system check says all fine.

Joomla version, 3.4.8.
joomdle_v1.0.5-for-joomla30
moodle-latest-30

Thanks in advance

Never mind. I fixed that. Only registered students could follow the link.
