Using WordPress API, E-mail field is not mandatory in Functions wp_insert_user and wp_update_user. So, the API let us insert/update user W/O E-mail!
I’m already adding users in WP admin “add user” page, W/O E-mail just by disabling HTML property “Required” of E-mail field using JS snipets, but you are requiring Emails in code, and I don’t want to manipulate plugin files!
I found the way!
1- temporarily, changed my sub2 root folder to wp folder (public_html)
2- in my network admin, added a subdomain same as sub2 to my network
3- changed lanuage, theme setting and header as needed and removed menu items (to hide menu!)
4- changed my sub2 root folder back to its folder
5- copied required and missing js, images and styles (inspected in chrome) to the same folder as called in my sub2 urls.
bang!
Wordpress theme loaded!
No page breaks!
