if you don't minl getting rid of the date you can add this to the CSS Inserts
HTML Code:
.comment-meta a {display:none;}
.comment-meta span a {display: inline;}
If you want the date, but not the link, then you need to edit bfa_custom_comments and find this code (line 22-23 in version 3.6.4
HTML Code:
<a href="<?php echo htmlspecialchars( get_comment_link( $comment->comment_ID ) ) ?>">
<?php printf(__('%1$s at %2$s','atahualpa'), get_comment_date(), get_comment_time()) ?></a>
and change it to
HTML Code:
<?php printf(__('%1$s at %2$s','atahualpa'), get_comment_date(), get_comment_time()) ?>
