If you are unable to move issues on your Agile board, it usually means that there are problems (and solutions) as described below.
With Javascript files
There are 2 options:
- they may not be copied properly from plugins/redmine_agile/assets to redmine/public/plugin_assets/redmine_agile/
- the folder plugin_assets doesn't have enough permissions (it should have the same permissions as log, files, and tmp, also there should be the same owner and group)
Lack of proper permissions
Otherwise, it can be related to a lack of proper permissions. A certain user (or you) has been allowed only to view the board. The last point to investigate is the correct setup of issue workflow.
To learn more about the configuration of permissions for Agile, please see this guide.
Agile modules not enabled (video demonstration)
If this is the case, then you need to just enable the Agile and Agile backlog modules for the specific project that the problematic issue belongs to. For better understanding the situation, please see this video demonstration:
