Hello,

I’ve problem with using OpenProject using polish letters. When I try to write anything with polish letters and save it, I’ve got error message:

Internal error

An error occurred on the page you were trying to access.
If you continue to experience problems please contact your OpenProject administrator for assistance.

If you are the OpenProject administrator, check your log files for details about the error.

There is such information in production.log:
