Thanks for getting back to me! Yes. The guide only mentions ShopWP. It does not mention WP Shop. As I know little to nothing yet about either, I don’t want to get into a situation where conflicts might arise on installation of your Pro version of ShopWP. If confirmed that I can follow the guide substituting WP Shop for ShopWP, I’m good to go on the upgrade instructions.
And thank you Bluehost for the response and links.
