Hi Bro,
I know what you mean, yeah “the Stay Connected” box
So you want to “erase” all the TagDiv things from your website. Just simply do these things:
1. Make sure you have logged in to your wp=admin
2. Visit your website, I mean the homepage where you see the “Stay Connected” box
3. Is you using Google Chrome, you’le see the menus under the address bar. Find the “Edit With TD Composer” button
4. Once you clicked that button, you’re gonna be on the TD Editor
5. Go to the right side off the screen. Point the “Stay Connected” box that you want to destroy lol
6. Point at the right above corner. Find the “delete” button and hit it.
7. The last step, make sure you hit the “floppy disk” (save button) on the left side bar of the editor.

Congratulations,
you do it well.
