Thank you, it seems to be working now. I have version 5.0.6 installed.
I had the same problem, our website crashed when upgrading from 4.4.12 to 5.0.5. Our server is virtual so I am thankful I took a snapshot before I did the updates and restored our website back. Is there anything I can do to upgrade to 5.0.5 or should I just avoid this update all together and wait for an updated version?
