I have another issue, the filtering options doesn't appear on this minisite. See the attached screenshot
There is another minisite with this issue http://sunkenrock.com/wallman/
I looked at those 2 minisite settings side by side with one without issue and nothing affecting those differs between the minisites "with" and "without" this issue. I though that maybe it could be from another panel in "theme-option" but then it wouldn't affect 2 out of 10 minisites.
It must have to do with your minisite front page. Are you sure the minisite front page is setup and created correctly? Especially because both of those issues are happening with the same minisite...
It was like a revelation when I read your response and I got my answer: the list type was set as "separated" while it needed to be "merged"
I had created that minisite way after the others so I had forgotten about this.
thanks a lot!
