Moodle for mobile

I just upgraded from Moodle 3.1 to 3.3.  On the Notification preferences page, I am getting this error in the header:

Unexpected response from the Airnotifier server: Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/tornado/web.py", line 1390, in _execute result = self.prepare() File "/usr/local/lib/python2.7/dist-packages/tornado/web.py", line 2103, in prepare raise HTTPError(self._status_code) HTTPError: HTTP 404: Not Found

Has anyone else experienced this issue?

Thanks!
