Redmine

I cant seem to get syntax highlighting to work. It didnt work from the beginning install.
I looked in my vendor\plugins folder and coderay is not there. However, it is in vendor\gems folder "coderay-1.0.0", probably from me installing it through gem later.

I checked my text formatting and it seems correct: code class="php" (minus tags).

I have redmine installed on
OS: centOs 5
ruby 1.8.7 (2011-12-28 patchlevel 357)
MySql 5.0.95

Thanks.
