What Happen if i turn it on but writers don't have adsense pub id?

Hi,
Yes, the plugin will check if the article author has set the adsense pub id. If it is not set, the admin ads will be served instead. So you don’t have to worry about that! ??

Best regards,
Plato.

thanks for your answer…last little question: is showing ads of two ifferent ids on the same web page against adsense’s tos?

Hi,
I don’t think it is against their TOS, but I am not sure. You better read their TOS or ask in the product support forums: https://productforums.google.com/forum/#!forum/adsense

Could you please take your time to rate the plugin?

Thanks a lot!
