why jquery is not loading in wordpress page?

There are two things you should try:

  1. WordPress loads jQuery in compatibility mode, so you will need to use the noconflict syntax, ex. jQuery('.text-white.follow').plate();. More information:

  2. If you are using a child theme, you need to call get_stylesheet_directory_uri() instead of get_template_directory_uri(). Parent theme assets are accessed using template, and child theme assets are accessed using stylesheet.
