UI breaks after upgrade to 5.1

Created by: illuminated

Hi all,

I have just upgraded to 5.1 and the pages' layout is a bit broken:

The whole main dashboard is also displayed in a single column.

Now, I have had to alter the previous version (5.0) to make it work. I have edited following files: .../gitlab/db/schema.rb .../gitlab/lib/tasks/gitlab/check.rake

I don't remember exactly the reason, but I believe it was something related to puma...

before fetching the 5.1 version, I've just deleted these files and fetched the 5.1 as per the upgrade instructions.

The Chrome inspector (and the tools there) are not showing that anything is missing.

So, how to restore back the UI?
