Hi xmas79,

 

Please ensure that you are using the latest "CuteEditor.dll", not the old one.

 

And remove the old reference of file "CuteEditor.dll" for you project and re-add it with the new "CuteEditor.dll".

 

The new version has not the control names "UploadSingleFile", not sure why you use this code. This is your own code? Or is a part of the editor files?

 

Regards,

 

Ken
