Hi Ken,

For multiple file upload, we made a test setting UploadType to CuteWebUI.UploadType.Silverlight, and the same error occurs ("FLM error xxx"). So it has defenitvely nothing to do with Flash.

 

And as state before, for single file upload we set UploadType to CuteWebUI.UploadType.IFrame, and we get the error "unable submit form, frame not ready".

 

In both cases, the error occurs only when accessing the web app from outside. From inside the network it works fine.

 

Don't you have any other idea?
