The screen shot of the missing Production section trying to edit
When click on Edit to edit a section of an article, for example,
the result page https://en.wikipedia.org/wiki/Blue_Jasmine?veaction=edit#Production appears to be a huge toolbar on top, and the section of "Production" is almost invisible - see attached screen shot.
Also, the toolbar should be clearly marked with visible borders to distinguished from the contents of an article. Now it's almost blurred into the article and very confusing.
