Just for repetition's sake, I want to do the following: I need to set custom fields and the excerpt metaboxes for WP default Posts post type when a new user is created. I know that by default WP doesn't show them but would like it to. I will be removing the Screen Options tab so the user won't be able to disable them.
I know this question has been asked for different scenarios and I have tried using and changing the code that I found here and on the web that help manipulate this but without much luck (eg: How to set default screen options?). Obviously I've tried on different installs but it doesn't work. Is there another way of doing this?
