I use Opera for WGT and quite a while back these ad banners with "This site can't be reached" started showing up. I think it's related to the built in ad blocking. If I resize the window I can make it go away. Just wonder if anyone knows why it started showing up and if there is any way to make it go away.
It's because the web site that hosts the banner ad is down, or the banner ad itself no longer exists there.
Try using an ad-blocker, or if you already have one, make sure it's turned on for wgt.com. That should make the banner you're seeing go away.
I am using an ad blocker that's built in to Opera. The ad blocker is doing it's job, if I turn off for WGT site I would get flooded with ads. Just wondering why the box started to show up, a while back it never did show up.
