I used TurnKey Hub to backup vTiger 5.2.1. Everything went well.
Used restore to migrate the 5.2.1 data into a fresh install of Turnkey vTiger 12.0 (5.4.0) and everything appears to work, but when I sign in to the appliance i get a blank page with the message: Migration Incompleted. Please contact your system administrator.
I've tried the migration from scratch 2 times. Not working.
What am I missing? Or is this a bug?
