WordPress blog excerpt not working in Themes

Some of the themes in wordpress does not display excerpt on blog page, category pages or archive pages. This is because theme does not include the experts code in the theme file.

This is a very simple tutorial that anyone can implement and take advantage of this built-in feature. The benefit of implementing this tutorial is that it decreases page load time and it increases the pageview count.

So we will have to update theme as per our need. For this process we will have to edit index.php file, archive.php file, and category.php file and find the code

<?php the_content(); ?>

If this is there then replace it with

<?php the_excerpt(); ?>
