Hi there I am owner of an articles directory. I am using adsense on my site. Since last week I am experiencing problem with ads shown on my articles pages. Ads are showing normal on all pages except on articles pages. I am using 1 ad on head and 2 ads on the article body. When I open any page of my article some times all ads shown, some times no ad is showing. In fire fox when I right click on the place of ads and from "This frame" click on "View Frame Source" I get "<html><body bgcolor="#eeeeee"></body></html>" If I see the "view frame info" I got address "http://pagead2.googlesyndication.com/pagead/ads? client=ca-pub-#*$!#*$!#*$!#*$!#*$!x& dt=1209575840140&lmt=1209575831& alt_color=eeeeee&prev_slotnames=4190199329& format=336x280_as&output=html& correlator=1209575838734&url=http%3A%2F%2Fwww.example.com%2Farticles%2F%3F Encouraging-property-development-and-lowering-carbon-emissions %26articleid%3D10612&color_bg=eeeeee&color_text=000000& color_link=0000FF&color_url=000000&color_border=eeeeee& ad_type=text_image&ref=http%3A%2F%2Fwww.example.com%2F& frm=0&ui=rc%3A6&cc=100&ga_vid=1831856674.1209571707& ga_sid=1209575794&ga_hid=558303376&ga_fc=true& flash=9.0.45&u_h=600&u_w=800&u_ah=570&u_aw=800& u_cd=32&u_tz=300&u_his=1&u_java=true&u_nplug=25&u_nmime=103" Please help me resolve this issue. I have checked all my coding and tried many options but they don't worked for it. If anybody have any suggestion please inform me. You can see this on the following url "http://www.example.com/articles/? Encouraging-property-development-and-lowering-carbon-emissions& articleid=10612" I remind you that some times it shows and some times not, so may be you will have to check some other articles urls on the bottom of the page. Thanks in advance.
