admin-hooks.php on line 160 error

hello, i am kind of new to wordpress but have experience in other cms. anyways i know this is a theme related error. the theme publisher does not provide support forums. so, i am relying on this community.

I am getting this error at the very top of my web page.

Warning: Creating default object from empty value in /home/snoringf/public_html/wp-content/themes/headlines_enhanced/functions/admin-hooks.php on line 160

I am pretty lost. this error lacks information with google search. so, any advice anyone can give me to go in the right direction would be absolutely appreciated. thank you

the error is on this site: http://snoringfree.com

thanks again!
