directory contents showed instead if GS page

[Carlos]

If there is a directory with the same name as a page in GS, its content will be showed rather than the page.

I find this a feature, :-) not a problem. It gives the possibility to easily add links in the site menus to other pages in the site that aren't created/managed with GetSimple but share the same directory (or are in subdirectories).

To avoid problems with a user creating a page with the same slug as a directory, you could use some "_" character in the directory's name:

SITE/_download/
SITE/download_folder/
