Problem with adsense

Hi

I’ve been having a few problems with running google adsense on my website
http://www.photoguides.net/
I’m using the ‘adsense manager’ plugin to run my ads as a widget.
I have an adsense account and ive put my ID in correctly, but whenever this plugin is running there are always errors on my webpage

On Safari 4 Beta i’m getting:
(16) Unable to post message to http://googleads.g.doubleclick.net. Recipient has origin http://www.photoguides.net.

On Firefox 3.0.1 i’m getting:
Security Error: Content at http://googleads.g.doubleclick.net/ may not load data from http://www.photoguides.net/.

Does anyone know what i can do to fix this? I dont want to be loosing all my clicks!

Thanks
