After upgrading to 1.0.6 (very nice, thanks!), I get the string strftimedmyw (<-exactly like that, in double parenthesis) displayed in place of the session date.
Could it have to do with missing translation entries (my site use Italian)?
thanks

ops! fixed: I had missed that I needed to copy the lang directory as well
