Please if anyone can check my site Recent Articles and let me know if can see 3 adsense ads, I just see two of them and can't make it work
I think I see them, 1 at the top, left and bottom? Try clearing your cookies and cache. It might help if you can;t see them, or you might have ads blocked on your computer.
Ok. I see three ad units appearing on the homepage. For the individual article page, there's only two appearing. One on the left sidebar and another one at the bottom. If you set the top ad unit to have only image ads appear, then there could be possibility to have no ads at all if they can't find suitable matching ads to your site keywords.
I can see right there in your site. your ad is already display. If you changed some code or update with your Adsense it will take up for about 10min to up or maybe a sec
