@hithunters thank you for reaching out.
1. We should never change anything in the core files. You mentioned that you have changed the default size in the pluggable.php
file, this is highly not recommended. It is because when WordPress will release a new update, all of its core files including the pluggable.php
will be overwritten and your changes will be wiped out.
2. Instead of changing the default avatar, you should use the following code in the file from where the avatars are loading on the site. Please read this for more information.
<?php echo get_avatar( $comment, 32 ); ?>
3. I have checked the site you mentioned and the avatar loading at the bottom of the blog post is not loading from the Simple Local Avatar, it is coming from the Gravatar. This means that you might not have set an avatar using the plugin’s (Simple Local Avatar’s) setting. Please go to the WordPress Back end > Users > Edit a user > Select an avatar > Save User. Read more here.
