a few months ago, I had Neos 2 and it worked wonderful. I remember that during installation, the installer lost its CSS but the installed Neos worked fine.
But now I created a new database and did the same instructions as I did when installing the newest Neos version. There is again no CSS during installation but the real problem is that 90% of the Backend is missing when the installation is over - see picture. The weid thing is that I can not even install an old Neos version, the Backend is away there, too.
I found one thing that bugs me: The folders in Neos_Ressources are both empty (Persistent and Static). In my old Neos they were full of stuff, I guess it was a bunch of symlinks. However if I goggle for missing symlinks in Neos I only find suggestions like giving permission to the user etc and I tried that already.
# enable the following line for production context
SetEnv FLOW_CONTEXT Production
Stuff I tried:
Adding/Removing Options -MultiViews in vhosts.conf and adding/removing FLOW_CONTEXT Production
Start XAMPP Control Panel als administrator
create new fresh database and install again
Give all users all rights in all files and dictionaries in the Neos folder
I emptied all Neos and browser caches that exist countless times
BTW Im forced to install Neos without composer. I will not be able to use composer commands.
