We are using mb setting page, metabox tabs and metabox plugin tu create new admin page in our WordPress, following your documentation Pencil example.We copy the code and paste in our project and we can see Admin page and Tabs, but not metaboxes.
Yes, we create metaboxe. We follow your documentation "Pencil" example, "Using tabs" option. If you see you documentation, you will see that creates 3 metaboxes.
We try also another examples but in all cases metaboxes not shows and we didn't see console or PHP errors. We don't know whats happens.
I'm not doing anything special, only copy the code. Can you please check that again? If you see anything difficult, please send me an email with temporary admin account, I'll take a look at that for you.
