You can not login to our Moodle with Ipad App, it stopped working about a week ago. Instead of being logged in you get an error message:
"Please check our login details or ask your site administrator to check Moodle configuration."
Then I tested it on demo.moodle.net after activating the mobile web service. Here the app shot down when I clicked on - I think it was content (I am not an Apple user, so I am not absolutely sure if I remember it correctly). Now when I open the app it shot down immediately, I get no change to try to log in to other installations.
I do not know which version it is, and I have no idea about how to find out. I have just set it to 1.1.4 in this tracker issue, assuming it is automatically updated.
