Well. Yes, im using the sectional one right now.
Im just not sure if I did everything which is neccessary.
Let me go through it again, maybe you get an idea if it's just a stupid mistake on my side:
1. Downloaded the Files Visual Index Section and Visual Index Main
2. Uploaded them to the plugin-folder, where all the different exhibition formats are listed as well
3. Created a new exhibition in my section "info" called test.
4. Left everything blank, chose the Visual Index Section theme and published the whole thing
From what I thought, this should have been enough. I though the plugin would gather all the images from the other exhibits in my "info"-section and display them in a grid as thumbnails. Did I miss something?
