Hallo @Alle,
ich habe upgedated - gemäß dem Link aus vorigem Post - und dann ging erstmal gar nichts mehr: config.php (war natürlich überschrieben).
Danach hatte ich denselben Fehler wie im vorigen Post… Habe dann lokal eine Shopware 5.5.1 installiert und die Tabelle “s_benchmark_config” von lokal auf meine Online-DB kopiert.
Wenn ich mich im BE einlogge - das geht wieder 
- dann bekomme ich ein Fenster “503 - Service unavailable” mit folgendem Inhalt:
Ups! Ein Fehler ist aufgetreten! Die nachfolgenden Hinweise sollten Ihnen weiterhelfen.

Ich vermute, dass ich da noch etwas durchlaufen lassen muss, nur was ist die Frage???
meine.domain/recovery/update zeigt nach 2 Sekunden meine Site: Kopfbereich da / Keine Inhalte / Fussbereich da
Kann sich bitte jemand die obige Fehlermeldung anschauen und mit helfen? Besten Dank im Vorraus…
