Here are the possibilities of URLs to access your site:

http://idtagsonline.com/shop
http://www.idtagsonline.com/shop
http://idtagsonline.com
http://www.idtagsonline.com
https://idtagsonline.com/shop
https://www.idtagsonline.com/shop
https://idtagsonline.com ***
https://www.idtagsonline.com

Entering any of these would be best if it resulted in the https://idtagsonline.com (the one with ***)

Your cPanel code does not cover that. AND, I'm not sure what cPanel is going to do with redirecting a non-existent directory.

Melanie would be the expert on this, but a 301 from a previous (and now deleted) directory could be problematic with the SEs.
