Cannot modify header after activation of a plugin.

    I’m creating a plugin and now I got a big problem with my WordPress admin. I always getting this error message.

    Warning: Cannot modify header information – headers already sent by (output started at /var/www/html/helge/wp-content/plugins/test01/hj-dvd-list.php:94) in /var/www/html/helge/wp-admin/inline-uploading.php on line 5

  • Try editing the plugin to remove any white space before the opening <?php at the top, or after the closing ?> at the bottom (including blank lines).
