error when using async file upload

When creating a form and using Telenik async file upload I get the following error whereas it works with either of the other upload types. Can anyone give some assistance?

  • HI Whitehouse, what version of Dynamic Forms and DNN are you using? Also, is this a site we can have host access to? IF so, can you email the credentials to dnnsupport@datasprings.com, referencing this forum post? Also provide us the URL of the dynamic forms page.

  • dynamic form 4.10.04 and DNN 7.3. I can't give direct access but I can screenshot anything you need. - Whitehouse 5/18/2016

  • HI, this version of Dynamic Forms is really old and we no longer support it. I would suggest you backup your website / database and then download and try out the Dynamic Forms 6.0 trial version and see if it resolves the issue with DNN 7.3.

    The trial version can be found here:

News plays a very important role in our society and especially in our lives. You can say that the edubirdie reviews is also a kind of news resource to us because it shares data along with the news. I was not into the news stuff before but now I know it’s worth.
