    Hello there,

    I downloaded trial version and i set up a blank page with Telerik's project template. I added Editor control from Toolbox. I did not set any properties of the Editor. Telerik.Web.UI.DialogHandler's all web.config setup was already in web.config.

    All editor dialogs are working properly in my development machine. My development machine and production server are using same version of IIS which is 7.5. I'm not using any URL rewrites.

    However, my production server shows blank page when pressing any manager dialogs and some of the dialogs are not working properly. What's the problem?

    Thanks in advance!

    Hi Gamze,

    The problem is due to some Firewall, Antivirus or WebSense tool that is blocking the RadEditor's dialogs URLs which size exceed the specified one.

    The RadEditor dialogs receive encoded arguments such as skin and configuration information (for example the ImagesPaths, DialogCssFiles) via the URL. In addition RadEditor follows the HTTP rules, which allow up to 2000 symbols to be used for the URL length. However, if some monitoring program such as WebSense or a Proxy server decrease the URL length for example to 1700 symbols then this will break the loading of the editor dialogs and cause errors like "The page cannot be found" or "Invalid Request" error or load blank dialogs.

    To fix the problem contact your network administrator and ask him / her to increase the allowed URL length to the allowed by the HTTP rules 2000 symbols.


    The problem is discussed in the following help article: Blank Dialogs Problem.
