8. Startpage plugin
9. Scrum Redmine plugin
The application gives an error "internal error"
Only following a direct link works. Network and browser - it doesn't matter. Those. using a link in a project to go to an object (task) does not work for some users who are not admins in Redmine. Admins don't have this problem.
How to treat? Where to look?
There is a lot of information in the "production.log" file, but the problem has not yet been localized.
I ask for your help, experts.

Answer 1

internal server error is definitely a 500 error, if you can't find it in the log, put the server in development mode and you will see an error in the browser
