I looked at the link but did not understand what to do.
My situation in includes/class-better-recent-comments-util.php is:
‘excerpts’ => true
…
if ( $excerpts ) {
$comment_text = get_comment_excerpt( $comment->comment_ID );
} else {
$comment_text = strip_tags( str_replace( array( “\n”, “\r” ), ‘ ‘, $comment->comment_content ) );
}
You’d need a developer to look at that, as you need to add some code to your theme or a custom plugin to do this. Sorry I can’ be more help
