I am having a problem with some of the tool dialogs in RadEditor.

I tried installing the latest release but the sale problem is occurring. The problem is with the Flash, MediaManager, LinkManager and TemplateManager dialogs, which all cause a 403 error. The First 2 dialog controls "ImageManager and DocumentManager" work correctly with no errora.
I have traced it down what I believe is the root cause which is the broken dialogs are generating a bad/truncated url that is missing the "Telerik.Web.UI.DialogHandler.aspx?" url portion.

Bad URL:


Good URL:


Do you have any idea why only some of the dialogs/tool have the incorrectly formatted URL and how I can resolve it.

Many thanks.

Some monitoring program such as proxy, firewall, etc is blocking the dialog URL due to its length. The problem is described in the following article: Blank Dialog Problem.

If you unable to fix it by reconfiguring this tool, you can solve the issue by reducing the URL length of the dialog using this code:
<script type="text/javascript">
function setUrlLength(editor)
  editor.get_dialogOpener()._dialogUrlLengthLimit = 500;
<telerik:RadEditor ID="RadEditor1" runat="Server" OnClientLoad="setUrlLength" />
