There was a problem. When migrating MagicInfo 3.1 (MIIPS-3106.1) to a new server (Windows Server 2012), the folder \runtime was copied, the PostgreSQL-database was copied and imported. Everything started, but when you open the Schedule-tab - an error occurs - Data Error. And error ocurs when you open Device-tab - "There has been an error. Please contact system administrator if the problem persists."
IP-address - identical.
