Hey @JB2012,
1.) We are glad that you watch the video tutorial about Footer Builder.
2.) I check your custom HTML footer in the widget area and you need to style it with CSS in order to mimic your desired colors and layout.
3.) I don’t see the issue here, would you mind explaining more information because the setup of your Footer Builder was set to a specific contact page called Contact.
4.) It was a plugin conflict with the Autoptimize plugin, I tried to disable the said plugin and the circle spinning was gone. To know how to improve the performance using the theme, you may check this doc.
5.) It was the same answer with the number 4
6.) The reason why the post carousel is not displayed on the other pages is that it conflicts with your custom footer in the widget area. A conflict between scripts, as you can see your about page doesn’t have a footer while your contact page is using the footer builder that’s why the post carousel is showing on that pages.
Hope that helps.
