Hi!
I created a CPT called 'Portfolio', set the Capability type to 'Custom', and then it disappears from my admin control panel. I installed User Role Editor and I see that the Admin profile is listed as having access to all of the Custom capabilities under the Portfolio CPT.
I also installed the Members plugin just to make sure that User Role Editor wasn't wrong, and the Members plugin also says admin has full access to all of the capabilities for this CPT... but I still cannot see it on the admin panel.
If I change the CPT capability back to Post, it shows up immediately after saving.
Help?
