 * Hey people,
 * Once in a while (few times a day) my sites goes randomly down and gives error:
 * Warning: Cannot modify header information – headers already sent by (output started
   at ../public_html/blog/wp-config.php:12) in ..//public_html/blog/wp-includes/
   pluggable.php on line 1207
 * If I refresh my site few times, it goes back up.
    I’m running WordPress 4.3.1
   running Independent Publisher theme.
 * Link to WP blog: [http://bit.ly/svtearly](http://bit.ly/svtearly)
 * I’ve tried everything and even contacted the Hostgator. Do you guys have any 
   suggestions, how to fix it?
 * Thanks so much!

 * Hello @muenzo@hotmail.com,
    This sort of error is generated due to various reasons.
   One of them is php tag and blank lines in your theme template files such as functions.
   php. index.php etc. So check those files if there are blank lines at the bottom
   and also missing php closing tag.
 * Thanks!

 * The error only happens, when there is “www” front of my blog. Any ideas?

 * I’m not seeing any error when I try to go to your site with a www in front – 
   it redirects to your website without www, which seems to be what you want to 
   have the site be seen on.
 * Are you only getting the error in the dashboard? When your site “goes randomly
   down”, do you mean that you get a white screen, or that you get messed up CSS?
   Or something else?
 * Did you check on the functions.php and other theme template files as suggested
   above?

 * Also, the theme you are using was last updated in 2014. There may be conflicts
   that have emerged with your theme and either WP core or plugins. Have you tried
   switching to a default WP theme to see if your problem still persists?
