    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.

     

     

    <httpHandlers>
        <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />
        <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" />
        <add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false" />
        <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false" />
        <add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false" />
     
      </httpHandlers>
    <system.webServer>
       <validation validateIntegratedModeConfiguration="false" />
       <modules>
         <remove name="FormsAuthentication" />
       </modules>
       <handlers>
         <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
         <remove name="OPTIONSVerbHandler" />
         <remove name="TRACEVerbHandler" />
          
         <remove name="ChartImage_axd" />
         <remove name="Telerik_Web_UI_SpellCheckHandler_axd" />
         <remove name="Telerik_Web_UI_DialogHandler_aspx" />
         <remove name="Telerik_RadUploadProgressHandler_ashx" />
         <remove name="Telerik_Web_UI_WebResource_axd" /><add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
         <add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode" />
         <add name="Telerik_Web_UI_DialogHandler_aspx" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" preCondition="integratedMode" />
         <add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode" />
         <add name="Telerik_Web_UI_SpellCheckHandler_axd" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" preCondition="integratedMode" />
         <add name="Telerik_RadUploadProgressHandler_ashx" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" preCondition="integratedMode" />
       </handlers>
     </system.webServer>

    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>
