Redmine

Good morning to everyone,

Since a couple of days I have started to receive the ‘Internal error’ message every time I want to create a new project or subproject. I work with Redmine 3.4.6.stable. I've checked the logs and I get the following error:

App 2120 stderr: Started GET "/projects/new?parent_id=cliente-gestioneinver" for 192.168.3.1 at 2024-10-17 17:17:07 +0200

I would be very grateful if you could help me with this error.

Thank you in advance.
