I have asp.net project that uses an AsyncFileUpload to allows user to upload local files to a database. I occasionally have a problem uploading files getting a message "Server Response Error unknown server error. Do you have to see the response page", I click Ok get Unhanded exception message and it repeats Server Response Error unknown server error. The box turn red and it won't let me continue.
I'm not sure I have the pattern down yet. But it is now a problem trying to load .png file in particular. If I convert the png to a jpg it work OK. It is a problem from my server not my development machine.
