I have AdSense ads on my site, but they don't appear on the computer that I mainly use.

If I use a different computer somewhere else they'll show up, but otherwise I can't see them. This is, of course, a really annoying problem.

Can someone just tell me the settings you need to have to be able to see them? I don't think it's a browser thing, because I have IE, Firefox and Opera, and can't see them in any of them.

Any thoughts?

You probably have the server delievering adsense blocked in your hosts file.

Look in c:\windows\system32\drivers\etc\hosts
Open the hosts file in notepad.
If you find any lines that contain the domain googlesyndication (or something like that) delete the line(s), Close and save. (dont save as, Just close and save changes).

If that doesn't fix it, Your computer may be displaying a cached version of that page, a version that doesn't have the adsense code in it.. Clear your cache.

Wow, thank you so much. This problem has been plaguing me for ages, and the solution was so simple. Thanks.

no problem, glad ya got it sorted.
