I can't get the Featured Image metabox to show up on the edit page for the default
page post types.
Though as opposed to this question, it does work for the custom post type I've created using a plugin. It just doesn't work with the default ones.
I've read the Codex Article on Post_thumbnails.
Added the following line to the current theme's
functions.php and to that plugin I was working on:
add_theme_support( 'post-thumbnails', array( 'post', 'page' ) );
Also been checking the screen options on the top right of the edit page and the checkbox for the Featured Image is not even there.
Where do I check to see if something else does not overwrite that? Please help
