Thinking about it twice, you may be right. The server is not on the same
host but may have been upgraded at the same time, and while I get the
error message on the client side, it may just be because the client
displays an error message sent by the server. I will check as soon as
possible, and if that's the case I am very sorry about the noise.
Thank you!
