There are random YouTube ads showing on my posts. I didn't put them there and I can't see them (having looked at the page on 2 separate computers and using all 3 browsers). Some of my readers can see them but not all. In fact, one reader saw it and then when she went back 5 minutes later, didn't see the ad! Is anybody else having this problem? What's going on and how can I fix it?
The blog I need help with is worcestercommissionforwomen.wordpress.com.
