The problem that i'm having is that i downloaded php,apache, and mysql pre-compiled(or configured) from Firepages. And it seems to be that they configured apache to work only for php. I tried what you told me but it still doesn't work.
Without knowing what they've configured it to do, I went to the Firepages site. Where's their documetation? Without knowing more about what you have there (what error message are you getting?), I'd have to recommend you take another look at Apache's docs on configuring for CGI. I know it sounds like a cop out, but that's how I did it after I broke my first Apache install. I'd bet that you just have to add pl to AddHandler.
