Subpage not reachable any more

I have a page “” which is not reachable any more (Forbidden)

What I noticed:

  1. When I request “” in the browser it gets extended to (with final slash). Who is adding that slash?
  2. Reuploading the “sub” pages under “sub2” works.

What might have caused it:
I defined a subdomain at my webhoster “” pointing to “/grav/sub” in my webspace

That looks like a .htaccess problem (if using Apache). If sub2 works and you have setup a subfolder rule for /sub, that might interfere.

The slash, same thing, looks like a htaccess rule. Grav does not add a slash.
