I would like to be able to make a Portfolio with Cornerstone, but am not able to see Cornerstone in Settings?
this is the answer I was trying to implement: "https://theme.co/apex/forums/topic/adding-portfolio-items-cornerstone-and-visual-composer-isnt-there/#post-608865
"For Cornerstone navigate to Settings > Cornerstone then allowed the post types you want to edit in Cornerstone.
