OK. I installed a new OpenACS 4.5 beta with general comments and static pages.
I had 2 html files in the www directory.
Here is the result:
/home/dave/develop/openacs-4-5-beta-1/www/test.html: added
/home/dave/develop/openacs-4-5-beta-1/www/test2.html: added
I am not sure where to tell you to look. Did you install and mount general comments?
