If you're seeing something like this on your homepage & blog, then you don't have Content Intense installed.
As an exclusive Superflyer member theme, Motiv8 builds on a previous months freebie (Content Intense) to provide members with a custom look and feel to match the Motiv8 theme.
If you have Content Intense, simply install and activate it on your Motiv8 site and everything will resolve automatically. If you do not have or want to use Content Intense, simply re-save the page and you'll have the default Divi blog grid in its place.
Please note that Motiv8 does not come packaged with Content Intense. Content Intense was a free member item during its initial launch in September 2017.
