Post content not showing up

I was never able to get the posts to show up so I downloaded a blog designer plugin and have been able to see the summary of the posts successfully, but STILL when you click on the Read More to read the rest of the post – I get nothing – not even the summary you see in the previous page. Blog designer said “I have checked your site setting and found that you have single post issue in your theme file.” so can you check the theme and see why the posts aren’t appearing?
