The last 2 post have not displayed a featured image on the blog page. On the home page there is the image, just not the actual blog. I don't recall changing anything. Does anyone know why this happened? I am using version 1.1.3.

Featured images don't display on a single post page since they are not part of the post content

Could the template be modified to display them? Would that be single.php?

I'm still new to WP and I've never done posts.

Yes, you can modify single.php. The Wordpress Codex is a huge help in learning how to edit your templates with certain functions. Searching it or even Googling will turn up an answer for you in most cases. Here is a page talking about what you want to do: http://wordpress.org/support/topic/h...ge-inside-post.

you can edit the 'single.php' virtual template and add

	<?php bfa_thumb( 620, 180, true, '', '' ); ?>

to it

I read and did everything you posted about featured image, but nothing worked out for me... Featured image disappeared after the update 1.1.8.
I did an update for 1.1.9, saved one post to clear the thumb cache, and reset Montezuma Options Sub Templates -> postformats.php. However, it still isn't working properly. What can be the problem? Is there any solution?

My blog is http://primetutoronline.com/

@ primetutoronline: first you shouldn't hijack someone elses thread, second I see featured images on your site for your post 'Учись всегда – учись везде!'

try changing the name of one the other images to an english name
