Nieuwe themplate maar blijft fout aan gegeven

Beste,

Op mijn nieuwe website: http://www.Dlightmedia.com wil de nieuwe themplate niet goed installeren en blijft hij het volgende zeggen:

me/dennispr/domains/dlightmedia.com/public_html/wp-content/themes/yoo_crystal_wp/warp/helpers/xml.php on line 39

Warning: session_start() [function.session-start]: Cannot send session cookie – headers already sent by (output started at /home/dennispr/domains/dlightmedia.com/public_html/wp-content/themes/yoo_crystal_wp/warp/helpers/xml.php:39) in /home/dennispr/domains/dlightmedia.com/public_html/wp-content/themes/yoo_crystal_wp/warp/systems/wordpress.3.0/helpers/system.php on line 196

Weet iemand wat dit betekent?

Mvg;
Dennis.
