Redirect on login error

I cannot redirect to any page, just to dashboard.
Whatever I choose it still redirects to dashboard and when i try to make a change in admin panel it shows that it can’t find that page.

Site is not in english language but it doesn’t have any strange characters in any page name.

I hope that you will be able to help me.

Thanks in advance!
