I have a website that is running WordPress 3.4.2.
I'm having a problem with email notifications related to comments on Posts. When a comment is submitted, the comment is saved but no email notification is received to the discussion email address.
Note: I create a custom post type called "Collections" with a capability_type => 'page'. I receive email notification on comments related to "Collections" post types but not "Post" post types.
If more information is needed, let me know.
