Upgrade from 6.2.2 to 6.3.1 - Can't access via browser

OK so I modified/added this to my /etc/apache2/sites-available/default-ssl.conf

seahub

##Not Working with 6.x RewriteRule ^/(media.)$ /$1 [QSA,L,PT]
##Not Working with 6.3 RewriteCond %{REQUEST_FILENAME} !-f
##Not Working with 6.3 RewriteRule ^(.
)$ /seahub.fcgi/$1 [QSA,L,E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

#WSGI Mode
SetEnvIf Authorization “(.*)” HTTP_AUTHORIZATION=$1
ProxyPass / http://127.0.0.1:8000/
ProxyPassReverse / http://127.0.0.1:8000/

and the server started

I ran

./seahub.sh python-env seahub/manage.py migrate_file_comment

I modified /etc/init.d/seafile-server to remove all the fastcgi stuff, setting the var FASTCGI to false

fastcgi=false

Now I can browser to the seafile BUT My custom color settings seem to be gone

seahub_settings.py does have the setting

BRANDING_CSS = ‘custom/custom.css’

and the custom file does exist
