500 Internal Server Error

This error can cause if the svmstack-fpm service is running instead of svmstack-fpm7 on the Master node:

# systemctl status svmstack-fpm7
● svmstack-fpm7.service – LSB: starts php-fpm7
Loaded: loaded (/etc/rc.d/init.d/svmstack-fpm7; bad; vendor preset: disabled)
Active: inactive (dead) since Wed 2021-06-02 22:28:29 EDT; 8s ago

# systemctl status svmstack-fpm
● svmstack-fpm.service – LSB: starts php-fpm
Loaded: loaded (/etc/rc.d/init.d/svmstack-fpm; bad; vendor preset: disabled)
Active: active (running) since Wed 2021-06-02 22:28:35 EDT; 4s ago
Docs: man:systemd-sysv-generator(8)
Process: 4432 ExecStart=/etc/rc.d/init.d/svmstack-fpm start (code=exited, status=0/SUCCESS)
Tasks: 1
CGroup: /system.slice/svmstack-fpm.service
└─4434 php-fpm: master process (/usr/local/svmstack/fpm/php-fpm.conf)

In order to fix this, our Support Experts suggest the following steps:

• Initially, we connect to the SolusVM Master node via SSH.
• Then we stop svmstack-fpm service and start svmstack-fpm7 service: # systemctl stop svmstack-fpm && systemctl start svmstack-fpm7
