Comments no longer working

2 days ago, my wife’s blog stopped accepting comments. Anyone not logged in gets a “Error: please fill the required fields (name, email).” message. Nothing had changed for anything. She hadn’t updated the theme in a while, so I updated it, but still same issue. I’ve searched many threads and no response.

url: lilmuselily.com
Hosting: Linux on Godaddy
Database: MySQL
Theme: Themify

Things I have attempted.

unclicking radio button requiring name and email (error goes away but comment doesn’t post)

renamed email and email2 in comment.php for Themify. (does nothing).

Below is the comment.php file.

<?php
/**
 * Template for comments
 * @package themify
 * @since 1.0.0
 */
?>

<?php themify_base_comment_before(); //hook ?>

<?php if ( have_comments() || comments_open() ) : ?>

	<div id="comments" class="commentwrap">

		<?php themify_base_comment_start(); //hook ?>

		<?php if ( post_password_required() && have_comments() ) : ?>

			<p class="nopassword"><?php _e( 'This post is password protected. Enter the password to view any comments.', 'themify' ); ?></p>

		<?php elseif ( have_comments() ) : ?>

			<h4 class="comment-title"><?php comments_number(__('No Comments','themify'), __('1 Comment','themify'), __('% Comments','themify') );?></h4>
