I just tried to upgrade Discourse from 1.4.x to 1.5.1 and the upgrade failed at the
rake multisite:migrate step with this error:
MiniProfilerRails initialized twice. Set 'require: false' for rack-mini-profiler in your Gemfile
Now when I go to the dashboard, this is what I see:
I’m pretty sure I’m still running the 1.4 codebase and yet when I go to the upgrade page, it says I’m up-to-date. It looks like the upgrade process is getting confused when there is an unexpected error happening during the upgrade.
I realise there are two bug reports here but the second one seems more serious to me.
