that doesn’t work for me
update: funny bug.
I got 2 custom post types from the previous version, plus 1 new.
the new one with the “show in menu” YES works.
Those two older types substitute each other in funny way.
Sometimes one of them is visible when the “show in menu” is NO, and when it’s shown in menu the next is automatically hidden. and so it goes on and on in circle…..the solution is bellow
It works, in a way, but you have to reload the admin page.
The reason why one was hidden and the other shown was that as I played with it the Admin UI reflects always the previous change, and because I was switching it off an on one by one, it causes this strange effect.
Simple solution. Reload the admin page after you make changes.
