Describe the bug

(https://mastodon.social/@ts-new@hub.tschlotfeldt.de/113596516493945482 made me aware of this bug)

Login procedure: If the user name is NOT correct the error message is strange/wrong in that case.

(Not correct means also that the user name is case sensitiv!)

The error message: "The web server seems to be incorrectly configured for cookies required for PHP sessions!"

(screen shot from demo.freshrss.org - user name -> I tried demos instead of demo)

To Reproduce

1. Go to login page
2. try to login with a non existing user
3. see the misleading error message

(reproduce-able on demo.freshrss.org too)

Expected behavior

I would expect a message like: "Wrong user name or password".
And I would not expect that there is an issue with the case sensitivity of the user name
