OK, thanks.
I have another question.
I have 9 custom post types, let’s call them CPT1 to … CPT9.
I would like to change the capabilities for user role Author for only one of the CPT.
Let’s say I want to remove “Edit post” only for CPT4.
Now whenever I remove the checkmark next to “Edit post” of CPT4 and click on “Update”, my changes apply to ALL POSTS.
How can I specify that I only want to change the CPT4 capabilities?
