Thanks a lot for the quick fixes Ofi.
Regarding the question on "Teachers". I already have a teacher displayed for two courses? If you click on the first and the last link from the dropdown menu of "Netværksmøder" at the main menu, you will see a teacher at the bottom of the course page. It's just important to me that the structure of my "courses" are the same. Please let me know how to either add a teacher to the last two or how it is removed from the other two.
The link you provided to the screenshot is not available.
I'm not sure where I should look the default.php file you linked to in order to remove the link from the teachers section of the page?
Thanks again.
