I was googling to find a solution for this forever, I was so close but still can't find the problem...
The closest solution I found was at this site But:
I want exactly the opposite of what this guy posted: Automatic line break in js SyntaxHighlighter
He wants instead of horizontal bar to break the code down, but what do I want is instead of breaking the code down, to display a horizontal bar.
I've used SH on multiple projects and never actually had this issue till now.
I've installed it in wordpress as a plugin in a custom theme, I modified the theme css file(s) and the syntax highlighter's file(s) (.css), but still nothing's going on.
Here's a screenshot
If you have any suggestion what the problem might be, please tell me - any help is appreciated.
