catwingz on "[Theme: Luminescence Lite] possible malware detected"

Hi, I am doing some cleanup on a site using this theme which was hacked.

Now I am getting an error message

Malware
Security warning in the URL: http://www.stuffadjust.com/before-after/
*Site error detected. Details: http://sucuri.net/malware/php-error-fatal-error?v6 <b>Fatal error</b>: Call to undefined function luminescence_lite_entry_meta() in <b>/usr/home/tekutoia/public_html/wp-content/themes/luminescence-lite/content-image.php</b> on line <b>30</b>

This is line 30: <?php luminescence_lite_entry_meta(); ?>

I have an old copy of the theme which leads me to believe that this code is a part of the theme, but given the circumstances it looks like a correction is in order. Help?
