Headers already sent error

Hi folks,

Im having some trouble with my Creativelife Theme, when i use it in my localhost it works perfectly but when i started upload it in my hosting and choose the creativelife theme, it shows this annoying error in the admin dashboard..

Warning: Cannot modify header information – headers already sent by (output started at /home/philcata/public_html/ginteno/wp-content/themes/Creativelife/haku/includes/helper.php:1) in /home/philcata/public_html/ginteno/wp-includes/option.php on line 563

I’ve been searching for a similar error online but i have not seen any answer that would help me to resolve this..

i will appreciate if someone here can help me figure out the solution thanks and god bless..
