The notices look to me like some did not get pre-created at install time. Unusual but, as I say, anjoying as opposed to a problem. As you update admin panels then they will get created properly and the notices will stop.

I really have no clue what the ‘VM’ in that error stands for. But yes – I would talk it over with your server management to see if they know. I am unaware of any problems with our autoupdate. Again it is something virtually all users leave turned on to the best of my knowledge. You could turn it off until the issue gets more light shed on it of course. And it will be changing in the forthcoming 5.7 release.
