php - Warning: Cannot modify header information - WordPress issue

I'm using WordPress 3.5.1 in my website,

I have copied this site into my local server for changes and everything went fine but suddenly after I uploaded my website to the public.html folder I get this error message when I try to use mysite.com:

(Warning: Cannot modify header information - headers already sent by (output started at /home/*/public_html/wp-content/themes/andrina-lite/functions/theme-options.php:660) in /home/*/public_html/wp-includes/pluggable.php on line 876)

But when I try www.mysite.com instead of mysite.com its opens but without the front page images that were uploaded by theme options.

Notes:

• in my local server all front page images had the same problem


• ***** is my directory name and is hidden by me in this post
