CanvasIframeApplication "Given URL is not allowed by the Application configuration."

[ghost]

When I use the CanvasIframeApplication sample I receive this message. I found on the Internet that I should specify the Website URL but it doesn't change anything. It does this when I try to connect with an user who hadn't authorized the application yet. I don't know why it doesn't work, as it worked pretty fine before.

Thanks for your help.

you have to register an app in facebook, and change the appropriate values in web.config

make sure you url ends with / in the facebook application settings in facebook.com

like

http://localhost/

http://samplefacebookapp.com/

please feel free to ask incase it doesnt solve.

i think this might help you. http://forum.developers.facebook.net/viewtopic.php?pid=262754

"yout might need to add to site URL to the app settings Settings->Web Site->Site URL."

for some it solved, others didnt. anyways you can try it out. if not I will recheck the CanvasIFrameApplication sample when im at home.

Thanks for your research but it doesn't work (already tried as specified in my first message ;)) I wonder if it's not a new bug on facebook, because it worked fine with your code, and now it doesn't work. I found this bug, which is only 2 days old: http://bugs.developers.facebook.net/show_bug.cgi?id=12463

if it was working properly and all of a sudden it stopped workin, its most likely facebook changed some stuffs.

2days back i had faced with a similar change in fb api, http://forum.developers.facebook.net/viewtopic.php?id=74494
