I'm not sure this is the right place but here goes. I've been trying to solve this for 3 days now and i'm about to go crazy now. Adsense wont show anything on my wife's site(inspirasiku.info). Just a blank space. Before it was fine.
For the sake of testing,I made a new wordpress installation on subdomain and paste the code there it shows up fine. I also made a html page on root directory with adsense code only, it shows fine too.On a wamp server on my laptop where i build up this site with exact same theme and configuration the ad also shows up fine.
I thought it was because W3 Total cache plugin. I put it back on preview mode(on the live site). Suprisingly i can see it all, make me crazier even more and want to bang my head to the wall. Still not satisfied I uninstall total cache and disable/uninstall all plugins. (Yes I manually delete remaining total cache configuration on .htaccess and wp-config.php)but yet no avail. Adsense still wont show.
Now i have a wild thoughts maybe got something to do on Cpanel or the database itself. I don't know... maybe i have lost my sanity.
Thanks for the suggestion netmag but if you read carefully when i use w3tc plugins and i put the site(live/real site) back into preview mode all of the ads are showing fine. So it's not google site i think. This proves it.
I'm beginning to think either wordpress itself(core or between plugins) or maybe the database itself or all in combination.
Geez!Looks like i answering myself as i type.Just realize that. I'm gonna check this out...
