I've tried several different articles with no luck. I'm using 2018.3.910.45. Any suggestions? It keeps referencing the smart tag, but I don't see anything obvious in smart tag.

Hi Joe,

Please use the information in this KB article to troubleshoot and solve the problem: Web.config registration missing!.

Usually the dialog handler rename does the trick:

Open the web.config file and replace Telerik.Web.UI.DialogHandler.aspx with Telerik.Web.UI.DialogHandler.axd

<system.web>
  <httpHandlers>
    <add path="Telerik.Web.UI.DialogHandler.axd" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false"/>
  </httpHandlers>
</system.web>
<system.webServer>
  <validation validateIntegratedModeConfiguration="false"/>
  <handlers>
    <remove name="Telerik_Web_UI_DialogHandler_axd"/>
    <add name="Telerik_Web_UI_DialogHandler_axd" path="Telerik.Web.UI.DialogHandler.axd" type="Telerik.Web.UI.DialogHandler" verb="*" preCondition="integratedMode"/>
  </handlers>
</system.webServer>
Set the RadEditor's DialogHandlerUrl property to "~/Telerik.Web.UI.DialogHandler.axd", i.e.
<telerik:RadEditor ID="RadEditor1" DialogHandlerUrl="~/Telerik.Web.UI.DialogHandler.axd" runat="server"></telerik:RadEditor>
