I figured it out finally.
For the Bootstore theme just edit the HOME page by going to wordpress.com and logging into your account for your website. Go into the admin and dashboard.
Then choose >Appearance and then scroll down to >Bootstore.
Scroll a little and you will see the 3 shortcuts section.
Fill in the fields, add a photo or graphic from your computer or your wordpress library from the tabs and upload a photo.
SAVE and you will be able to see it.
This was a pain to find out and it took all morning for anyone to simply share this very simple solution. Now you don’t HAVE to create another home page or a static page. The template is nice but seriously it took all morning. I added this because I hope it comes up on searches for the next average person who is frustrated with complicated instructions on these forums. This really works.
