 * Pressbox plugin in 3.3.x complains about invalid header.
 * solution: edit the plugin and delete the top blank line below `<?php` and above`/*`
 * update the plugin and then go active it from the inactive list.
 * enjoy

 * yeah, ironically, I realized that afterwards. I wished I could find another solution
   but the code the guy uses in the plugin is really complex.
