Hey Mike thanks for your quick responce. I did find the bug eventualy. The category name you use in the query and which is used bij the generator take the name/title of the category. I got it working by using the category url “name” which in my case differs somewhat from the title. Now its working properly.
I’m having the exact same problem.. just plain simple [wp-tiles category=category-name] doesn’t work. Tried it with and without ” and the same for – inbetween the category words 🙁
