I just installed the product on my 3.22 site www.dia-seminare.org
I enabled 'social' FB like in articles and it shows up in every article. This is too much, so I want to disable, but it is still there!
All like plugin places are set to 'none'

I hope that helps, but if you run into anything else, just let me know.
