Hi,
On a J3.10.6, we have try to upgrade from a very recent K3.1.6 to 4.0.2 with very little database (10 comments maybe ?).
After 20 min it stuck on Initializing Database Synchronization and the BO show a us a wonderfull 0 Class 'FH' not found

What is the next best move ? Of course we have backup and can reverse back but if you have some ideas to finish this nicely...
Hello Nicolas,

Can you provide us your backend and FTP access so that we could troubleshoot the installation issue directly on your site?

Hi Horst,

You may want to create a new thread with the access details to your site so that we could troubleshoot it.
