Hi,

Just recently, ads on some websites have stopped displaying. In place of the ad is a large solid red box the size of whatever ad should be visible. This doesn't happen to every ad, just some.

Any ideas of what could cause this?

Thanks

absolutely no idea from what you have told us!

Is this in your browser?
somebody else's
every machine?
your website?
some other website?

something else?

Its most likely not every? machine nor every website. As I mentioned in the post its not my site but rather "some websites" & not "every ad, just some". It seems to be random.

It is my computer and my browser however. It happens in both ie6 and firefox.

Here a screenshot, the red areas are where ads should be: http://i44.photobucket.com/albums/f8...hes/Noname.jpg
