Contao Kopie erzeugt 500 Error

[Filotronik]

Hallo,

bei einem derzeitigen Projekt sollte ich aufgrund einer Seitenüberarbeitung eine Kopie der Seite erstellen (Contao 3.5.28). Diese habe ich auf einen Testserver bei 1und1 gezogen und sobald ich die Seite aufrufe, lädt entweder nichts oder ich erhalte einen 500 Error.
Meine .htaccess habe ich bereits bereinigt und auch durch "http://www.htaccesscheck.com/" durchlaufen lassen, selbst wenn ich die Datei komplett lösche lädt die Seite auch nicht.
Ebenfalls habe ich schon versucht Contao im coreOnlyMode laufen zu lassen, dann lädt zumindest die Errorseite von Contao.

Installierte Plugins sind im Screenshot anbei zu sehen.

Hat jemand eine Idee?

Anbei die Fehlermeldungen bei jeweils aktivieretem coreOnlyMode und ohne diesen:

Ohne coreOnlyMode:

Dei Datenbankszugangsdaten sind wohl falsch, denn sonst würde es kein Verbindungsproblem geben:

Uncaught exception 'Exception' with message 'Connection refused' thrown in /homepages/44/d141589236/htdocs/_greenmech/system/modules/core/library/Contao/Database/Mysqli.php

(Du solltest Deinen Post oben noch bearbeiten und die Zugangsdaten entfernen).

Läuft die Kopie auf dem selben Server wie das Original? Die Fehlermeldungen deuten jedenfalls darauf hin, dass die Verbindung zur Datenbank fehlschlägt, also dass die Verbindungsdaten nicht passen.
