In a new website, I installed Meta Box + AIO and created a custom post type, as I always do. However, this custom post type does not show up in the WordPress menu. I also cannot determine its position in the menu.
Installed is WP 6.5.2. Is that the problem? As I have installed other plugins and a theme that never ever conflicts with Meta Box.
Sorry for the late reply. Can you please change the CPT slug to another one and check this issue again? You can also deactivate all plugins except Meta Box, MB extension plugins, switch to a standard theme of WordPress and see how it goes.
Weird, as I already did this and it didn't help. Now it does. Not one of the themes or plugins is giving trouble, but just deactivating and reactivating ánd deleting the post type and making a new one was enough. Thanks.
