Ok, I have a site right here:
The yellow boxes are where the adsense is supposed to be showing. I've tried disabling any plugins to see if they were causing the problem and I've also tried 2 different plugins, but the ad's never show! The current plugin I'm using to display the ads is ELI's WordCents adSense Widget with Analytics. The light yellow boxes are where the ads are supposed to be showing and nothing is coming up...
