I have a domain at http://qotr.net that I'm trying to set up as an app so that I can use OAuth. It was set up a few weeks ago, and we just now finished implementing the OAuth hooks on our application, when Facebook started giving us errors.
Now, when I go to the settings page, and edit anything, I get:
Error App Domain: qotr.net is not a valid domain. Site URL is not a valid URL.
I have: qotr.net
for the app domain and http://qotr.net
for the site url.
http://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fqotr.net
Tells me that it can't parse qotr.net. The site is clearly up and usable, and Google OAuth works.
I can't find anything online on why it might not parse correctly; any ideas?
in the App Domain, enter your site domain without the http:// or the www. Just put in, say for my website iamzang.com
For the site URL below the page, enter http://iamzang.com/
That will do the trick. I got the same error before and with this the domain is no longer invalid.
