Redmine

This ticket was created because of a request for help from the forum. I created it because Rub Version 2.7.2 was released in the User Guide... RedmineInstall
From: Maickel Neitzke

After logging in, I created a custom field and I can't edit it anymore.
Depending on the type of field created, different parts also fail redmine related to that type. When you exclude the field, everything goes back to normal.

Environment:
  Redmine version                4.2.3.stable
  Ruby version                   2.7.2-p137 (2020-10-01) [arm64-darwin21]

Problem solved.

I installed the 2.6.9 Ruby version and the issue not happened anymore.
