Redmine

Hello colleagues,

I have problems after migrating and updating Redmine from 4.2.3 to 5.1.1

This Redmine was moved from one server to another. Now in version 5.1.1 I get the following error when creating new user groups (attached screenshots and log captured in a local simulation environment).
