Reporting in with a problem likely accountable to the update being performed.

In attempting to post a new thread in one of the sub forums, I hit the Enter key too soon in the title bar and got a "operation failed, less than 5 characters in the title" error and my iPad mini completely locked up to where I had to hit the Home button to shut Safari down. Never seen that before.

If it's happening to me, that means it will/has happened to other Apple devices.
