I need to have a custom page with the top level of categories because simple seo does not like

index.php?main_page=index&cPath=0

Instead of diplaying all my categories , I get kicked back to the homepage..

So what I'm trying to do is display all the categories on a custom page called, similar to ez pages...

Well I followed the how to make a custom page, that was easy, but trying to dissect the code and functions is tough.. All I need is my categories displayed for cPath=0 on a custom page..

Does anyone know which variables to change, do I have to include something like $_GET[cPath]=0; ? .. what's the correct way to fix this? I've seen some other people with similar problems but no answers.

Thanks, I'm looking for an answer, but just some suggestions would be a great help too!
