Your custom blog post content will never show up in the Showit app, it will only show on your live blog.
If your custom blog post content is not showing in your Blog Template Pages inside of Showit, have no fear, that is how it's supposed to be!
Your blog template section in Showit simply dictates the design and style of your blog pages, but the content is all housed in your WordPress blog. Only on your live site can Showit & WordPress communicate at which time your custom blog content will be auto-populated from WordPress into your Showit blog design.
