Login/Logout Fehlermeldung 404

Hallo liebe Gemeinde, habe mein Projekt fast erfolgreich zu Ende geführt, doch habe allerdings noch ein kleines Problem mit der Login-Funktion. Ich brüte nun schon einen ganzen Tag am Script, doch ich komm nicht weiter. Ich habe eine geschützte Seite angelegt (Internes). Wenn ich mich einlogge, komme ich automatisch auf die Startseite, will aber direkt auf die geschützte Seite Internes. Wenn ich dann auf dieser Seite bin und ich mich wieder ausloggen will, bekomme ich eine Fehlermeldung (404). was mache ich falsch?

hier die login daten: username: test, password: test
