Neo Freeman on "[Theme:gamepress pro] No ads show up"

I used two ads slots, yet none is available.
Login, theme option, ads, Header ad+ad space #1
Here is my google ads code.
<script type="text/javascript"><!--
google_ad_client = "ca-pub-1900534021532757";
/* Tester 01 */
google_ad_slot = "7805067025";
google_ad_width = 320;
google_ad_height = 50;
