LCD Screen says "Updating - Do Not Unplug" (updating system from V8.5)

[mjseeley (Mark Seeley)]

Hi,
I now have a new installation fully updated and ready to go. I’ve ensured it is updated, and have imported the backup through the web interface import utility. It appeared to progress well untilI got the following errors:

I also get an error on the Web GUI:
**Notice** : Trying to get property of non-object in **/var/www/emoncms/Theme/basic/menu_view.php** on line **144**

Also:
Database error, you may need to run database update

I’ve seen reports of this last error and the requirement to do a manual database update using the PHP script described here, however the script doesn’t appear to be available in that folder:

Updating the database

If you are running an emonpi you could try php /home/pi/emonpi/emoncmsdbupdate.php This how the emonpi updates the database after updating emoncms here’s the script content https://github.com/openenergymonitor/emonpi/blob/master/emoncmsdbupdate.php

Any thoughts as to the next steps?
