I was never able to see a post show up in the upper right hand corner of my posts. I spoke to WPDirect (WordPress) support, and they told me that the Adsense ad that I'm trying to get to show up in the upper right hand corner of posts might not be showing up because I had 4 ads in the Adsense unit that shows up the body of the text.
They told me that you can only have 3 ads per page, and eluded that that may be the reason why the one in the upper right hand corner isn't showing up.
So, I swapped out the unit that shows up in the body of the text of the blog posts so that it only contains 2 ads, and the unit that I'm trying to get to show up in the upper right-hand corner (that's using the Adsense All in One plugin) still isn't showing up.
Is it showing up for you when you visit one of my blog posts? If not, do you have any ideas as to what's going on here? Thanks!
