I have installed the latest version this week. Now I am having AJAX error when uploading. The error occures when I click next on the first file upload screen after selecting a file. The upload still seems to work after you click OK on the error. This is a serious issue for me at the moment. The issue only manifests in IE9 and IE8. Chrome and Firefox work fine. Rad Ajax Upload Error

The error is a result of IIS not correctly configured to handle the upload progress callback. This calls a specific aspx page. The specifics depend on the IIS version you are running. The most likely cause is a clash with another handler. Note the quickest solution now is to switch to the regular asp.net upload provider (Upload Settings on Admin menu of DMX). Peter

Hello Peter, Everything was working fine until I upgraded to the latest DMX version. Not sure why the handlers would have been changed with the module upgrade? The actiual error is: RadUpload Ajax callback error. Source url returned invalid contents. If you provide an email, I can send you a screen shot. -Jason

Hi Jason, In a version not too long ago I had to change the handler name as DNN added one using the exact same name as they bought into Telerik. The upgrade script running in DMX should have renamed the handler for DMX but if for some reason this couldn't edit the web.config then it's broken. Check the web.config admin page of DMX as well (Admin menu when logged in as host). You can contact me on info/peter at bring2mind dot net. Peter

I am having the same problem. Do you have the entries that should be in web.config for both raduploader and dmxraduploader.

I've written a blog post about handlers: http://www.bring2mind.net...yId/94/Handlers.aspx Note that the order of handlers is also important. Recently I debugged an installation with many many handlers. Just moving the handler up resolved the issue. Peter
