I think it depends on the httpaccess. If i have a url like this: mydomain.com/someid the site thinks it´s a subfolder.
On other sites i got it working with a change like that:
RewriteRule ^([a-zA-Z0-9_-]+)/?([a-zA-Z0-9_-]+)?/?([a-zA-Z0-9_-]+)?/?([a-zA-Z0-9_-]+)?/?$ index.php?s=$1&a=$2&b=$3&c=$4 [NC,L,QSA]
But i don´t know Kirby good enough to find a working way to implement it to the httpaccess.
Is there any way to change the rewrite rule, that it´s possible to use that kind of deeplinking?
