    Invalid headers are usually due to white space found before or after <?php ?>. I have not fully investigated wp_deckbox_mtg.php so I cannot confirm if this is the same location and exact error occurring for everybody but at least for me that was where the error was occurring. What I did was delete very last line in the file which was white-space, once deleted, the invalid header warning disappeared.
