Any idea why the ad I created in my sidebar shows up in one browser and not another?
I am using IE11 also. It is an image ad. But, today when I checked it, it was showing the ad in IE too. I'm not sure why it didn't show yesterday when I created it. It showed it instantly in Firefox. For some reason it took longer for IE to show it. I am serving my content over CDN (Cloudflare) to speed up the load speed of my site. I wonder if that could have something to do with it, but if it did, you would think it would have taken just as long to show in Firefox. So, I don't know - strange.
