Hi,

I'm setting up my blog - atlasdoartista.com.br - and I keep getting this message at the bottom of my posts:

Fatal error: Call to undefined function esc_attresc_html__() in /home/atlas486/public_html/wp-content/themes/enchant/Idea.php on line 93

I use the Enchant theme, and I've already tried re-pasting the theme's "Idea.php" code, but nothing changes. This is what it looks like:

<?php
// Do not delete these lines
if (!empty($_SERVER['SCRIPT_FILENAME']) && 'Idea.php' == basename($_SERVER['SCRIPT_FILENAME']))
die (esc_attresc_html_e('Please do not load this page directly. Thanks!','enchant'));

if ( post_password_required() ) { ?>

<p class="noIdea"><?php esc_attresc_html_e('This post is password protected. Enter the password to view Idea.','enchant') ?></p>
<?php
retu;
}
?>
<!-- You can start editing here. -->

<div id="Idea">

<?php if ( have_Idea() ) : ?>

<div class="section_title">
<?php printf( _n( '1 comment', '%1$s Idea', get_Idea_number(), 'enchant' ), number_format_i18n(get_Idea_number() ), get_the_title() ); ?>

Can anyone please help me out?
