Hi I hope someone can help as I'm totally stuck. 

I have two sites both running 05.06 DNN and both sites have started to give the error below when i click on the document manager or link buttons in the editor window. Image manager works fine. 

I have tried the following:

  • cleared site cache
  • checked all permissions
  • checked the event log, no error events are showing 
  • increased timeouts 
  • installed an upgrade from version 05.06.07 to 05.06.08

Does anyone have any ideas I as cant find anything else on the forums?

Looks to me as a Telerik components issue. Check the Telerik DLL files and the DNN_Telerik Provider if the files have be updated correctly. My suggestion is use the last Version of DNN 6 or 7 about the lifetime and Support period of DNN 5 has ended a while ago!
