Blank Pages in Section - not resolved to date - please help

APPENDED June 11: This install gives strange errors in a host sitethat runs other CMSs OK. Still not resolved - can anyone help?

---

Hi, First thank-you I installed and a site where I could work on content inside three hours - amazing! This promises to be the best CMS I have seen.

But I seemingly have something set up slightly wrong:

After setting up my site, I populated it with the first option that puts in sample articles, blogs etc.

Then in Files · My blog · My jive discussion board · My manual · My Section I clicked on cover section. It gave me a blank page with the URL pointing to a php in section with an ID=.

THIS also happened when I clicked on my site map (balnk page).

THEN I clicked on modify this one - that took me to an editor space, into which I typed a basic article. When I hit SUBMIT once again I got a blank screen with this URL: http://www.morethanoil.com/articles/view.php?id=1

However, opening another tab in my browser I see the submit was taken??

What have I got wrong?

Thanks Zaph

PS: This CMS is amazing!
