I installed dokuwiki on the server and I found that mysite/dokuwiki/doku.php?id=wiki:syntax is a blank page while mysite/dokuwiki/data/pages/wiki/syntax.txt is not empty.
Moreover, when I check or edit the source of the empty syntax page, then I see the code there (see the demo below).
So, I wonder is this a feature or a bug? and I guess this has nothing to do the file permissions as such.
