This have been fixed in MyBB 1.6.9
and the editor.js file would not go in the header include but your root dir jscripts folder
and add <script type="text/javascript" src="jscripts/editor.js?ver=1608"> Template "codebuttons"
well change 1600 to 1608
just upgrade to 1.6.9 and I believe this should be fixed
