I have the following problem with gadgets on my EPiServer site: when I switch to "Start" tab in my admin interface and click "Add Gadgets..." button, I see a message "Failed to add gadget" with empty detailed error message. Using firebug I can see that the page makes request to http://localhost/UI/Shell/Dashboard/GetGadgetDefinitions/?_=1295005213076&pageSize=10¤tPage=1 and the request fails with error 404. Can anyone advise on the issue? It seems that there is something with configuration, but my config files are just copied from another environment where everything works fine. Paths to Program Files/EPiServer/etc are correct too.
