Fehler beim erneuten Verbinden mit der Datenbank

Das bedeutet, dass wir die Verbindung zum Datenbank-Server unter localhost:3306 verloren haben. Möglicherweise ist der Datenbank-Server deines Hostings derzeit nicht verfügbar.

Bist du sicher, dass der Datenbank-Server läuft?
Bist du sicher, dass der Datenbank-Server nicht überlastet ist?

Wenn du unsicher bist, was diese Begriffe bedeuten, solltest du lieber den Support deines Webhostings kontaktieren. Wenn du dann weiterhin Hilfe benötigst, kannst du stets die WordPress-Support-Foren besuchen.
