I had debugged it and found a solution. When a moderator approves my post, you can all see how to correct the code above and where to input the line in header.inc.php
Basically you DON'T even put in that code there, but under the refresh button code, so it does not interfere with your staff reply panel by breaking out the tabs.
Please see link for full details and the image.
