Package: zabbix-frontend-php Version: 1:4.0.4+dfsg-1 Severity: normal Dear Maintainer,
php7.3-opcache raises the following error when accessing to the Zabbix 4 login page: PHP Fatal error: Uncaught Error: Unsupported operand types in /usr/share/zabbix/include/classes/core/ZBase.php:111\nStack trace:\n#0 /usr/share/zabbix/include/classes/core/ZBase.php(119): ZBase->init()\n#1 /usr/share/zabbix/include/config.inc.php(33): ZBase->run('default')\n#2 /usr/share/zabbix/index.php(25): require_once('/usr/share/zabb...')\n#3 {main}\n thrown in /usr/share/zabbix/include/classes/core/ZBase.php on line 111 The consequence is a blank login page on the first access. A simple workaround consists in reloading the page. It can also be fixed by disabling opcache in /etc/apache2/conf-available/zabbix-frontend-php.conf: <IfModule mod_php7.c> php_value max_execution_time 300 php_value memory_limit 128M php_value post_max_size 16M php_value upload_max_filesize 2M php_value max_input_time 300 php_value date.timezone Europe/Paris -> php_value opcache.enable 0 <- </IfModule> Best regards, Pierre -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=fr_FR.utf8, LC_CTYPE=fr_FR.utf8 (charmap=UTF-8), LANGUAGE=fr_FR.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages zabbix-frontend-php depends on: ii fonts-dejavu-core 2.37-1 ii php 2:7.3+69 ii php-bcmath 2:7.3+69 ii php-gd 2:7.3+69 ii php-mbstring 2:7.3+69 ii php-mysql 2:7.3+69 ii php-xml 2:7.3+69 ii php7.3 [php] 7.3.3-1 ii php7.3-bcmath [php-bcmath] 7.3.3-1 ii php7.3-gd [php-gd] 7.3.3-1 ii php7.3-mbstring [php-mbstring] 7.3.3-1 ii php7.3-xml [php-xml] 7.3.3-1 ii ucf 3.0038+nmu1 Versions of packages zabbix-frontend-php recommends: ii apache2 [httpd] 2.4.38-2 ii libapache2-mod-php7.3 [libapache2-mod-php] 7.3.3-1 ii php-ldap 2:7.3+69 ii php7.3-ldap [php-ldap] 7.3.3-1 zabbix-frontend-php suggests no packages. -- Configuration Files: /etc/apache2/conf-available/zabbix-frontend-php.conf changed [not included] -- no debconf information
