"Moodle version must be 2.1 or greater" error message when using 2.2

See : http://moodle.org/mod/forum/discuss.php?d=189261

... The challenge is that the error message the Moodle for iPhone app is giving me states that "Moodle version must be 2.1 or greater".

However, I'm on 2.2 latest. So the error message isn't valid.

Can you help me to troubleshoot the problem a little more? Like is there a "debug" option I can turn on to get more information?

I could give you a temporary login on our site if that would help.
