 * I’m getting a notice and a warning when I try to trash a post or update something:
 * Notice: Undefined index: vsw_noncename in /mysite/wp-content/plugins/video-sidebar-
   widgets/class-postmetavideowidget.php on line 296
 * Warning: Cannot modify header information – headers already sent by (output started
   at /mysite/wp-content/plugins/video-sidebar-widgets/class-postmetavideowidget.
   php:296) in /mysite/wp-includes/pluggable.php on line 881
 * ¿Any hints about this? I have tried to fix the Header Information issue by removing
   spaces in the file as the codex says but without results, so, probably is another
   thing.

 * Hi,
 * That is a PHP undefined index notice, which shows up due to your PHP error reporting
   setting. You have E_NOTICE enabled.
    For your reference, [http://www.php.net/manual/en/errorfunc.constants.php](http://www.php.net/manual/en/errorfunc.constants.php)
 * This may happen to any other themes or plugin codes.
 * When I initially developed my plugin, I did not take that into account.
 * The quick fix is to suppress that by adding a @ before that line of code.
 * So you can open up video-sidebar-widgets/class-postmetavideowidget.php go to 
   line 296 and add a @ before it.
 * For your reference on @ symbol.

 * You can contact me via email if you need any further help troubleshooting on 
   your server. I will need you to setup on a live server and not your localhost.
 * You can find my email at my website’s contact page.
 * Thanks!
    Denzel
