I have a website that uses Telerik as editor. It's a custom build website. A couple of weeks ago I noticed the editor didn't work anymore on my Mac (iOS Catalina 15.10.7), the content field doesn't load and I get a shitload of Failed to load resourse errors in the developerwindow. Included is a printscreen of the editor. At first I thought it was because of the latest version of Java, I installed the day before, because the editor still worked on my 10-year old Macbook which hadn't been updated. 

That all changed today, when I wanted to create a new news item and got the same black content field als on my Mac. Does anyone have an idea what could cause this problem. This is a huge problem for me, because the way it is right now I can't publish new items anymore and that's devastating for an online Motorcycle magazine. Normally this is a issue a website developer should solve, but the guy who custom build our website has vanished, so now I've turned to this forum to hopefully get an answer.

Hi Ed,

There are many reasons for this generic error like URL rewriters, incorrect IIS, or web.config configurations.

Please check out the following resources which provide multiple suggestions of how to fix the issue: 

Also make sure you add location tags for the ASP.NET and Telerik handlers in the web.config file as instructed here:

 

<configuration>
  ...
  <location path="Telerik.Web.UI.WebResource.axd">
    <system.web>
      <authorization>
    <allow users="*"/>
      </authorization>
    </system.web>
  </location>
  <location path="Telerik.Web.UI.DialogHandler.aspx">
    <system.web>
      <authorization>
    <allow users="*"/>
      </authorization>
    </system.web>
  </location>
  <location path="ScriptResource.axd">
    <system.web>
      <authorization>
    <allow users="*"/>
      </authorization>
    </system.web>
  </location>
  <location path="WebResource.axd">
    <system.web>
      <authorization>
    <allow users="*"/>
      </authorization>
    </system.web>
  </location>
  ...
</configuration>
