Dem Modul php-imagick fehlt die SVG-Unterstützung. Für eine bessere Kompatibilität wird empfohlen, es zu installieren.

sudo apt-get install libmagickcore-6.q16-6-extra

The PHP OPcache module is not properly configured

The OPcache interned strings buffer is nearly full. To assure that repeating strings can be effectively cached, it is recommended to apply opcache.interned_strings_buffer to your PHP configuration with a value higher than 8.

Die Dateien

sudo vi /etc/php/7.3/apache2/php.ini

und

sudo vi /etc/php/7.3/fpm/php.ini

editieren und jeweils folgenden Einträge einkommentieren:

opcache.enable=1
opcache.enable_cli=1
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.memory_consumption=128
opcache.save_comments=1
opcache.revalidate_freq=1

Danach die Konfiguration neu laden:

sudo systemctl reload apache2.service
