@410455544 in case of Redmine 5.0.2 you have to use [corresponding branch of the plugin](https://github.com/Loriowar/redmine_issues_tree/tree/5.0.x). `master` branch doesn't contain any working code. There [is more explanation in the Readme](https://github.com/Loriowar/redmine_issues_tree/blob/master/README.md#compatibility).

It might works, but for Redmine `5.1.0` need to create new branch and properly compare and migrate all modified partials/views. In such approach, this will be checked plugin release compatible...
