syntax highlighter evolved plugin with long line

Hello I like this theme and trying to apply it to my technical site where I put syntax highlighter evolved plugin.

I noticed that, when one line of the code is long, the entire page width is changed as a result. Please see the link above. In comparison, this would be the normal page width that I expect:

This behaviour (page width extended due to long line in code) does not seem to be a problem with my old theme.

The page I need help with: [log in to see the link]
