whenever I try to access my Facebook applications when I am logged out. But when I log in to Facebook first THEN access the URL, I am able to resolve the application. Apparently, I wasn’t the only one experiencing the problem http://forum.developers.facebook.com/viewtopic.php?pid=96845#p96845 First reported in January this year and until now this issue has not been closed.

THE FIX:

1. Edit the settings of your application –> Enable Developer Mode –> save

   
Wax On…

SAVE!

2. Edit the settings of your application –> Disable Developer Mode –> save

 
Wax Off…

SAVE!!

3. log out and try to access your Applications URL

This worked for all the apps I was having issues with so I hope it works for the rest of you guys too. A few people were reporting how the application would resolve in their dev sites but then would cease to work once they ported them over to their Test sites. Highly likely, once the developers have the application and deploy it into a test scenario, they don’t bother going into “Developer Mode” before spreading the application which is probably why they are experiencing this. I hope they fix this soon. I’m relieved that my apps work fine now…
