MySQL server has gone away

Niet mogelijk de database te selecteren

Het is gelukt verbinding te maken met de databaseserver (dit betekent dat gebruikersnaam en wachtwoord correct zijn), maar het is niet mogelijk de database perlakantoor_dev te selecteren.

Als je niet weet hoe je een database moet instellen, neem dan contact op met de hostingprovider. Als al het andere niet gelukt is, kun je hulp vragen op het WordPress-supportforum.
