Last time I was changed the code in section-pagecolumn.php file for to display excerpt text in three column services section but the code is changes to the original one.
I have now again change the code in this file at line no. 59 to display the Excerpt text
<p><?php echo wp_trim_words( get_the_content(), of_get_option('pageboxlength'), '' ); ?></p>
<?php the_excerpt(); ?>
Please don’t modify the code in section-pagecolumn.php file
