Something I can fix, or just start from scratch.
I am trying to put together a version 15 system to test. Downloaded all OK.
When I use the 14-15 upgrade tool, all the tests come back OK, but when I proceed to the Upgrade process I get a nice orange bar at the top of the page
Call to private method module_functions::generate_unique_id() from context
And it just shows ERRORS in the Submitting data to servers line
