Most wikis with customisations had to make adjustments to accommodate fluid width. While Wikia could have made the transition easier by allowing individual users to toggle fluid width on their wiki, they did allow people to set up test wikis with fluid layout in order to make these changes in advance of the full rollout.

As far as I remember, the search bar has always been part of the right rail, so the line under the page header has never extended under the search bar.
 * under "XXX pages on this wiki" and search bar, there is a line, which can be replaced by image.

Could you please show me an example? I do not understand why a fixed-width "line" image was used in the first place, and would like to help fix this issue.

I'm unsure what "local navigation header" refers to. Could you also please show me an example of this? I would also like to help fix this issue.
 * Another: local navigation header image:

Solution: style="width:100%", or a class to do the same.
 * Tables on pages: wider screens end up having big empty spaces on the left and right of the tables (that's if the table was intended to take the whole width and no text on it's sides).
