I think that is not the actual error that Rémi is experiencing- the 492 case (which is indeed an invalid http error code) only happens when one actually klicks the link in the mail above(which I guess some did and you found in the logs) because the actual BF client will add a parameter to the "Target" URL.
The actual "errors" dont seem to show up in the lighttpd logs afaiks.
Oh, sorry. I was checking the one called "target", I assumed that was the URL that failed.
Assuming for the original ones the ts is part of the URL, none of that is still in the logs. Or are they post parameters? Do we know exactly which URL is actually failing, and when (exactly) this happened?
