I encountered a problem with my two sites on Zenphoto version 18.104.22.168  (Official Build) which has both with modified Default theme. They both have the same problem when I want to create Dynamic Albums.
It works fine if I change it to the Default theme. Only Admin Toolbox can create Dynamic Albums. Admin Toolbox shows however, when I click on it nothing happens. I know I can’t do anything with this but I would just like to hear some helpful tips from you.
