Ok, new info.
Mautic works, but not dashboard. When I try open dashboard, then I got errors like posted above.
Still database upgrade did not pass. Give errors like above.
For now I see two problems:
STILL EXIST:
- update database - Update to 5.1 - doctrine:schema:update problem · Issue #13845 · mautic/mautic · GitHub
SOLVED:
- php error in dashboard After update to 5.1 dashboard dosen't open · Issue #13844 · mautic/mautic · GitHub
There is a bug in stored configuration for Best Email reads hours widget.
