I am using version 1.3.9h, new install yesterday.
When checking on security needs, it advised this version had all new patches, etc.
I easily added a category and product, and actually purchased one and got clear thru to delivery, pay by check. No problem.
I connected with paypal and activated the paypal web standard.
I then can still do the following, open site, open admin, see the home page, navigate to other pages, click on new product icon and go to details, page. All this without logging in. Then when I tried to re log in, it gave me white page, Access Denied. I was able to go back to home page, navigate to product details page, and then when I attempted to add to cart, again the white screen with Access denied. No problem going back to active page.

I read a lot of things on here, but nothing seems to address just this type of reaction. Please advise what might be issue. If it is something I can adjust in Admin, no problem, I can open it just fine.
