Answer 1

I kept getting this error, when using wildcard subdomains with my app. I had the site url set to: http://myapp.com and app domain also to http://myapp.com, and also the same value for the Valid OAuth redirect URIs in the advanced tab of the settings app. I tried different combinations but only setting the http://subdomain.myapp.com as the redirect value worked, of course only for that subdomain.

The solution was to empty the redirect fields, leave it blank, that worked! ;)
