Hello/Hi/Greetings,

I seem to have an issue with the contact form.
When a user is logged in, the contact form works perfectly, but when an unregistered user tries the contact form he gets this error message for every input field :

Warning: Undefined array key "is_logged" in /customers/a/7/5/diehardagnetha.com/httpd.www/gallery/_data/templates_c/sp1c2o_v1b8i4^2f2fd6cadcaab89c02d386f0a1a76233ef9c4c9f_0.file.contact_form.tpl.php

on lines 86 and 101

here are the lines from line 86 to 105 :

<?php if ($_smarty_tpl->tpl_vars['contact']->value['is_logged']) {?>
          <?php echo $_smarty_tpl->tpl_vars['contact']->value['author'];?>

          <input type="hidden" name="author" value="<?php echo htmlspecialchars($_smarty_tpl->tpl_vars['contact']->value['author'], ENT_QUOTES, 'UTF-8', true);?>
">
<?php } else { ?>
          <input type="text" name="author" id="author" size="40" value="<?php echo htmlspecialchars($_smarty_tpl->tpl_vars['contact']->value['author'], ENT_QUOTES, 'UTF-8', true);?>
">
<?php }?>
        </td>
      </tr>
      <tr>
        <td class="title"><label for="email"><?php echo l10n('Your e-mail');?>
</label></td>
        <td>
<?php if ($_smarty_tpl->tpl_vars['contact']->value['is_logged'] && !empty($_smarty_tpl->tpl_vars['contact']->value['email'])) {?>
          <?php echo $_smarty_tpl->tpl_vars['contact']->value['email'];?>

          <input type="hidden" name="email" value="<?php echo htmlspecialchars($_smarty_tpl->tpl_vars['contact']->value['email'], ENT_QUOTES, 'UTF-8', true);?>
">


The input fields can be filled and when "send" is clicked, an email is sent.

The error occurs in Firefox, Chrome and Edge.
