Hey there,
wanted to try grav and did a fresh install based on the grav-core+admin and some skeletons which all resulted in a 404 “The requested URL …/admin was not found on this server”; disregarding which of the .zips I tried. Neither the skeletons, nor the core .zips contained an /admin folder on the highest hierarchy, where some redirect seems to point.
Would be glad if someone could point out my error and help with the fix. Thanks!
Skeletons don’t come with Admin preinstalled.
Grav+Admin on the other hand does, you maybe missed the .htaccess file? See the page not found doc
