I followed the directions located at https://docs.fogproject.org/en/latest/installation/server/install-fog-server/
I downloaded and ran the installation script via:
(I renamed the old fogproject folder as “fogproject-old” because git clone and git pull threw an error)

sudo -i
cd /root
git clone https://github.com/FOGProject/fogproject.git
cd /root/fogproject/bin
./installfog.sh

The upgrade process seemed to go well enough and I did not notice any errors. I got to the
“you still need to install/update your database schema” prompt. I clicked the link that was presented in the script and Firefox presented me with a blank white page and nothing else.

I waited quite a while, pressed a key, and the installation script finished.

Now when I try to visit 10.46.10.40/fog/management it throws me to http://10.46.10.40/fog/management/?node=schema and delivers a HTTP ERROR 500.
Rebooting did not help.

Please assist, and thank you in advance for your help!
