Yes, I'm getting red X's in Jenbel's post.
The first URL is:
http://www.flyertalk.com/forum/thumbsdown.gif
edit to add:
Now working again, and the URL is :
http://www.flyertalk.com/thumbsdown.gif
Notice that the 2 URLs I just posted are different. The URLs changed from when I first posted and did the "edit to add."
So right now, it's the URLs with "/forum/" in them that don't work, and ones that don't contain "/forum/" do work.
