I am! The same thing has happened to https://www.thelasvegasrealestateblog.com Very erratic display…sometimes it does, sometimes not. My sidebar & Header adsense ads have no problem showing up. Strange. This actually first began with my FeedFlare from Feedburner connected to AdSense – That worked fine for 2 weeks, then simply quit. I thought that the FeedFlare may be the problem, so I disabled it & tried this plugin. With the plugin, ads have shown once…after may reloads. I am going to let try and let it take its time. Not quite sure what the deal is.
Don’t know if that helps, but at least you know you’re not alone. Will you check my site to see if you see ads, or just white space below the post?
Thanks!
