So I wanted to change adsense around a little on a site. Well the ads don't show up!!! So I changed them back to how they were originally and they still don't show up!!! This was on the right side. I didn't touch the ones on the header and they are fine. Why won't the ads show up anymore??? It's just a blank space even though they were fine earlier and are the exact same codes they are earlier.
make sure you are copying/pasting everything properly.. this happened to me once because I was messing up the code after i was pasting it in.
This might be because adsense dont have any ads to show for your site and you have selected blank color if no adsense dont have inventory to display. This happens often with new sites
Did you remember to paste all of the code ? Try to generate a new code or copy the one in the header and paste it somewhere else.
maybe try to generate new code and then implement the new one. if still not show up, let us know again here with your url. we may can help.
