Hi I'm having this error for several days now. But the strange thing is that it doesn't happen all the time. It's more like a random error.
I know this error usually means that the html file is missing, but html is there and working. I have this error in production and only in a few cases. This happens with some users who log in my system from their machines. I can't reproduce this error, it just happens. I know it's not enough information but perhaps someone had this problem before. I can post stacktrace if somone considers it useful. Thanks in advanced. Tito
