I have a strange problem on the Custom Fields List Page.
On the summary it says that I have 4 Field Groups Published, which is true, but on the List Table only 1 shows up.
(Please check this screenshot: http://d.pr/i/gnLy)
Any ideas why there are 3 items missing ?
Okay, I found out it was a conflict with a posts_clauses filter I had on my custom theme. It had nothing to do with the ACF plugin.
Problem solved.
