I'm not sure whether it's a Perch-Issue or something else but anyway: The site I made is in a subfolder and it works perfectly: https://www.kris-zauberer.de/kris-zauberkunst/
My thought was to test it here, finish it and later on create an internal redirection to the subfolder from the main domain. But it doesn't work.
The index.php can't find the Perch-Content.
Where do I go wrong?
