Ho provato ad abilitare il certificato SSL. Namecheap mi ha fornito un file e l'ho usato sul file ..cf.crt. Dopo aver visto questo errore ho provato a convalidare tramite il metodo DCV. Ma ho ancora questo errore. sudo service apache2 restartnon fornisce alcun output.

Fare

apachectl stop

Verrà visualizzato un messaggio di errore relativo all'errore di sintassi nel /etc/apache2/apache2.conffile

Correggilo.

Quindi fa

apachectl stop
/etc/init.d/apache2 start

Ora il ricaricamento di apache2 funzionerà

Fare

/etc/init.d/apache2 reload
