PHP Meta Suddenly Not Working

This is what I have for the top of my author templates.

<div class="authortemplate">
<div class="authortemplatepic">
<?php echo get_avatar( get_the_author_email(), '215' ); ?>
</div>

<div class="authortemplatename">
<?php the_author_meta( 'firstname' ); ?> <?php the_author_meta( 'lastname' ); ?>
</div>
<div class="authortemplatecontent">
website:
</div>
<div class="authortemplatebio">
<?php the_author_meta( 'description' ); ?>
</div>
</div>

All of a sudden, just happened today, it’s not showing any of the meta data for my users. Was there an update or something?
