 * Hi,
 * I’m getting this Notice and Warning:
 * > Notice: Trying to get property of non-object in …/wp-includes/post-template.
   > php on line 208
   > Warning: Cannot modify header information – headers already sent by (output
   > started at …/wp-includes/post-template.php:208) in …/wp-content/plugins/luzanky-
   > web-plugin/lib/ExternLib/wp-session-manager/class-wp-session.php on line 123
 * I can get rid of the Warning by disabling the luzanky-web-plugin, but the notice
   remains…

 * OK, it seems it’s a WP core bug. I’ve reported it:

 * No, it’s NOT a WP core bug… see here:
    [http://core.trac.wordpress.org/ticket/24827](http://core.trac.wordpress.org/ticket/24827)
 * The problem seems to be here:
 * > The ​Content Headings Tree plugin uses the _get\_the\_content()_ function outside
   > the loop without passing any arguments, which is the source of the error.
 * This is a **serious issue**.
