Hello,

Sorry for the late reply.
-What type of blog are you using? To change the “Full Blog” excerpt text length, you have to edit one of these files:
includes/view/blog/loop-grid.php
includes/view/blog/loop-index.php
includes/view/blog/loop-second-style.php
includes/view/blog/loop-timeline.php

Find these lines:

<div class="text">
    <?php   if($post_format == 'video' || $post_format == 'audio')
              echo codeless_text_limit(get_the_content(), 20);
      else
         echo get_the_excerpt();    
    ?>
</div>

replace this line: echo get_the_excerpt();
with this echo codeless_text_limit(get_the_excerpt(), 20);
The value “20” means that there will be displaying up to 20 words from excerpt. Increase it to show more text.

-The “Post Masonry Grid” is a Visual Composer element not overwritten by theme code. So to edit it’s excerpt text length, you have to edit the plugins files.

Best regards!
