Hi,
Please try the solutions provided in this forum thread: Radeditor - 404 - File or directory not found:
- decrease the dialog URL length and see whether this will fix the problem:
<scripttype="text/javascript">
function setUrlLength(editor)
{
editor.get_dialogOpener()._dialogUrlLengthLimit = 500;
}
</script>
<telerik:RadEditor ID="RadEditor1" runat="Server" OnClientLoad="setUrlLength" />
If this does not help, try the following:
- Open the web.config file and replace Telerik.Web.UI.DialogHandler.aspx with Telerik.Web.UI.DialogHandler.axd
- Set the RadEditor's DialogHandlerUrl property to "~/Telerik.Web.UI.DialogHandler.axd".
More information on the dialogs configuration can be found in this article too: https://www.telerik.com/support/kb/aspnet-ajax/editor/details/error-web-config-registration-missing!-the-telerik-dialogs-require-a-httphandler-registration-in-the-web-config-file-.

I found solution,
IIS => Request Filtering => Rule => Someone add rule deny select, update.
I just remove rule and it's okay.
Thank for your help.

Can you please share which rule you have exactly removed to solve the issue? A screenshot could be very useful.
This could help your fellow developers.
Thank you!
