When i'm creating a new post type from Metabox, the post type that i'm created is not displaying on the WordPress admin panel. Is that any solution for it? I am using Metabox (Version 5.4.8), Metabox AIO (Version 1.15.2) and Oxygen 3.9 RC 2.
UPDATED: if I enter a long slug it won't display, however if I enter a short slug it display normally
.
