Very hard to say without actually seeing how it is set up.
But try this by moving all files under your /wordpress/ folder to the same level as /wordpress/
i.e. was:
wordpress/news
now:
wordpress/
news/
If any of the files contain directory specific links including wordpress, they will have to be manually changed.
A simple test is to create the news/ folder in the same level as wordpress and put in a file called hello.txt just containing the word "Hello" and then try to access it: www.site.com/news/hello.txt
