Cannot create new issue into a subproject
When I want to create a new issue into a subproject, I only have a limited number of fields displayed (Status, Files, Watchers).
If I click on create, I get the an error saying that "Subject cannot be blank", but I can't even see the field. However, I have created multiple Trackers, Issue Statuses, Enumerations...
Here is some additional information :Environment:
- Redmine version 4.0.1.stable
- Ruby version 2.5.3-p105 (2018-10-18) [x86_64-linux]
- Rails version 5.2.2
- Environment production
- Database adapter Mysql2
- Mailer queue ActiveJob::QueueAdapters::AsyncAdapter
- Mailer delivery smtp
- Subversion 1.7.14
- Git 126.96.36.199
- no plugin installed
Any insights would be greatly appreciated, I'm really confused.
