Hi,

With DMX 5.3.5, I'm getting a "RadUpload Ajax callback error. Source url returned invalid content:" error message when I use the RadUploadProvider.
I didn't see this error message with DMX 5.3.2
I'm only seeing this error message with the IE browser.
I don't get the message with Chrome or Firefox.
The site is running DNN 5.6.0

Here's how I get the error message:
1) Using IE8, on the "Upload/Choose Item" page, I select file to upload
2) Click on the NEXT button
This is where the error message window pops up.

Clicking OK closes the error message window and allows me to continue with the upload process.

Here's a screenshot of the error message:

Here's a snippet of my web.config file

How I get rid of the error message?

Thanks!

Hi Ken,

1. First item to check is whether the handler is in the handlers section in the web.config. The path as you see in the error message should be there. There is an admin page in DMX (Admin > Web.config) to verify and switch this as well. Make sure you have the right IIS version.

1b. There is a small snag under .net 4. If you run your website as a .net 4 website then you may need to remove the preCondition="integratedMode,runtimeVersionv2.0" to preCondition="integratedMode"

2. Do you have any 3rd party modules that do funky url rewriting? (thinking of URL Master) They sometimes interfere with traffic.

3. Is the IIS Url scanner active? A customer had the URLScan ISAPI filter on and this prevented some calls.

Hi Peter,

Thank you for the response!
In our case, 1b. was the problem.
Changing the preCondition value as you suggested fixed the problem.

Thanks again!

Same issue as original post with:
- DNN 07.01.02
- DMX 6.1.6
- Windows Server 2012 IIS8

RadUpload will not toggle to ON in Admin > Web.config

None of the above points seem to apply.

The following references to radupload appear in web.config. Is anything else needed? Can I add manually?

References in web.config as mentioned above:

add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI" preCondition="managedHandler"

add name="RadProgressHandler" verb="*" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.Upload.RadUploadProgressHandler, Telerik.Web.UI" preCondition="integratedMode"

add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI"

add verb="*" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.Upload.RadUploadProgressHandler, Telerik.Web.UI"

The RadUpload part is obsolete. You should be able to select the RadUpload provider in the Upload settings and it should load the RadUpload when uploading files. Can you confirm?
