Hello

We are trying to install RedmineUp Agile Pro Plugin on Redmine 4.0.4.

Installation worked fine but when i try to use the Backlog on a project, I obtain an Error 500.

Messages in the log begins with /

Error 500 ActionView::Template::Error (Mysql2::Error: Operand should contain 1 column(s):Operand should contain 1 column(s)

Do you have any idea what can cause this error ?
