Configuration Error - RadUploadHttpModule

[Jibber4568]

Hi guys,

We have recently upgraded to the latest rad controls as well as .net 4.

Most things are working fine however there appears to be an issue with the upload module. Upon click of the button I am returned the error:

Configuration Error 

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Could not load type 'Telerik.Web.UI.RadUploadHttpModule'. (C:\inetpub\wwwroot\..............\web.config line 80)

I have tried making various changes to the web.config but can't seem to get anything to resolve the issue. 

Below are the system.web and system.webserver sections from the web.config file. If you could point out where we are going wrong it would be greatly appreciated.

Thanks.

Please, let's do a test, change the value in the tag like this:

  <httpRuntime maxRequestLength="102400" executionTimeout="3600" />

How big do you need to release the maximum upload?

This article can help a lot for this case:

Any questions, just re-enter,

Tks

Thanks for that. I made the change but it didn't make any difference.

I'm not actually getting to the point at which I can upload a file, this is simply clicking on the button to load the uploader.

Thanks.

Hi Jibber4568,

You should register your RadUploadHttpModule in the <modules> section (within <system.webServer> section) of your web.config file.

Please refer to the following help articles here and here regarding the necessary registrations in the web config which have to be made.

Greetings,
