Image Manager 404 when deployed

[Adrian Barnes]

Image Manager dialog in the Editor works fine on my development machine.  When I upload to a development server (over which I have no control), I get a generic 404 error message (conveniently it doesn't tell me what page it's looking for).  Below are excerpts from my web.config.  Any ideas?  I tried the article on changing the extension from aspx to axd (http://www.telerik.com/community/forums/aspnet-ajax/editor/telerik-web-ui-dialoghandler-aspx-404.aspx), but I get the error that the dialogs need to be added to web.config if I do that.  Thanks!

Hello Adrian,

Please, try the fourth suggestion in this KB article:
Error: Web.config registration missing! The Telerik dialogs require a HttpHandler registration in the web.config file:

1. open the web.config file and replace Telerik.Web.UI.DialogHandler.aspx with Telerik.Web.UI.DialogHandler.axd
2. set the RadEditor's DialogHandlerUrl property to "~/Telerik.Web.UI.DialogHandler.axd"

Greetings,
Rumen
