I can't go to the: forum, course etc.

Hi
System check is ok!
But:
kursy.metafrasis.pl/pl/component/joomdle/course/5

There is no link, buttons there, which start quiz or forum.

You will need to create your own links, menu items etc. For example if you want a simple quiz, you will need to create the quiz in moodle and then publish the joomdle module for quiz in Joomdle. For forum, you need to configure in Moodle to use the Joomla Kunena forum.

Have I understood your problem correctly?

The following link:
kursy.metafrasis.pl/pl/component/joomdle/course/5

Show me the : one forum , one quiz.
It is open in IFrame.
I see that when I use MOODLE I can start course, but from joomla I can not. As you can see there isn't any link to start quiz or open forum...


Or maybe its because I am not logged in?

You need to be enroled into the course for links to appear.
