Hi contactlovelexington,

Go to Dashboard -> Settings -> Reading and choose your latest blog or use post page (your blog page). From onwards WordPress 4.4.1 post page as blog page will not work. Your settings must be below screenshot.

If you want to display blog full content template on other page then it works but to display on front page it will not work. By default you will have blog image large with read more button.

To have blog full content you need code customization for it. Go to theme folder -> inc -> structure -> content-extension.php on line no 162 you will see this code
<?php the_excerpt(); ?> remove this code and add below code
<?php the_content(); ?> and also remove the line no 173

<?php
						echo '<a class="readmore" href="' . get_permalink() . '" title="'.the_title( '', '', false ).'">'.__( 'Read more', 'interface' ).'</a>';
						?>

Better make a child theme and then customize the code. So that while updating to new version your customized code will not be lost. Otherwise you need to make same customization each and everytime you update to new version.

Thank you!
