The OS Gallery PRO module is not visible in the Components overview. And when I click in Extensions, the component "OS ImageGallery Pro" is available, but it is a version 1.0.3 Nov. 2013.
As you can see at
aboutlearning.dk/referencer/referencer-menu, it has been used previously
I have searched under "Extensions" "Find updates" but nothing appears.
What should I do to use the module?
