XF 1.5 ads after first post http error 400 on IE and nothing on chrome

#1
I am testing ads after first topic post on my localhost. I get error 400 on IE and nothing shows on chrome. I've made new 728x90 google banner and added this to ad_message_bellow:

<xen:if is="{$post.position} == 0">
my adsense code..
</xen:if>
