I’ve actually been encountering the same problem. I’ve seen it on two different sites, each on different servers and using different themes.
Just to add to Duncan’s post, I noticed that it’s only the “Thank You” message that doesn’t appear. The other messages–such as error messages–still work with the tracking code in place.
I’m not any good at JavaScript, but I’m guessing it’s probably some kind of issue related to scripts conflicted with one another? Or not?
Either way, any help is greatly appreciated!
