Hi Ken,

Kenneth:

Can you try the uploader on a normal page not in the iframe? Does it work? the iframe point to the same domain?

The uploader works on a normal page. 

The iframe points to the same domain.

Kenneth:

 

Do you get the same error on http://www.ajaxuploader.com/Demo/select-multiple-files-upload.aspx?

No, I'm not getting any errors on this demo page.

Is there a problem when using the uploader inside an iframe in FF? Could you please check this and maybe post a working example configuration inside an iframe? As I already mentioned there were no errors with the old 2010 dll.

Regards

Vladimir
