I am facing the same issue (Multiple references of telerik DLL) while upgrading the DNN version from 04.09.00 to 05.06.00.
Before update, I am using telerik version 2008.3.1125.35. After updation it automatically updated to version 2010.2.929.35(This is the default verison of telrik DLL provided in the DNN version 5.6).
I have checked in web.config file, as you mentioned in above reply:
1. (Before updates, these lines are not available in the web.config, below lines has been added after updation)
2. Check the version of telerik DLL in the bin directory, found that it has also been updated from
2008.3.1125.35 to 2010.2.929.35.
Run the application with the above settings (Web protal has been run successfully, but this time it is using telerik version 2010.02.0929.353 and we are facing lot of designing issues with the new version of telerik DLL)
Our basic requirement is to upgrade only the DNN version bot not Telerik DLL verison.
3. Removed the reference of telerik DLL 2010 verion and again added reference of old 2008 telerik DLL version.
4. Changed the settings in web.config file.(Chnaged the newVersion attribute value to the 2008.3.1125.35 )
4. Also checked in GAC, No telerik DLL is available/ installed in GAC.
5. Run the application . with the new settings.
Again found the same error (Multipe reference for telerik DLL )
