    Hello,
    OS: Debian 9.13, Apache 2
    I have just upgraded my ISPConfig with default settings, as I usually do. Unfortunately, instead of standard login page, I saw 500 Internal Server Error Apache screen. I have checked my Apache logs and they look like this (tail -f):

    [Sun Nov 08 10:21:32.534634 2020] [core:error] [pid 27127] [client 89.77.211.XXX:63899] End of script output before headers: index.php

    What has happened and how can I fix this? All webistes and PHPmyadmin work well, I just cannot login into ISPConfig.

    PHP 7 CGI package is missing. run:

    apt-get install php7.0-cgi

    to install it.

    Something is definitely wrong...

    Yes, many PHP packages are missing. I wonder how your system worked before as any older ISPConfig version required the same packages. Install the missing packages with this command:

    apt-get -y install php7.0 php7.0-common php7.0-gd php7.0-mysql php7.0-imap php7.0-cli php7.0-cgi php-pear php7.0-mcrypt php7.0-curl php7.0-intl php7.0-pspell php7.0-recode php7.0-sqlite3 php7.0-tidy php7.0-xmlrpc php7.0-xsl php7.0-zip php7.0-mbstring php7.0-soap

    Awesome, thanks! My ISPConfig works again.
    Yes, I also wonder what happened and how it worked before. Could be that PHP 7.0 got accidentally removed during the last system upgrade. Anyway - now I know what was the reason for the 500 error.
    BTW: What is the best PHP version for ISPConfig 3.2 and which configuration file defines it?

    Keep the system php version the same as what ships with your OS version; the settings for that are under server config. Then you add additional php versions for any other versions which you want to use for your websites.

    I am fucked... :) Same issue, same debian... After upgrading ISPCONFIG Multi (main) from ISPCONFIG 3.1.latest to 3.2
    first server fatal error.
    Than I installed all missing PHP for 7.0/7.1/7.2/7.3 none of this is working.
    Now /usr/bin/php --version

    PHP 7.2.34-8+0~20201103.52+debian9~1.gbpafa084 (cli) (built: Nov 3 2020 14:33:21) ( NTS )

    I am trying to access :8080 panel from different domains with different PHP... without success... Here are my logs

    This is main interface to run all settings for multiserver. So now It is not accessible. I need to fix it fast.

    I dont want to rollback to backups because I got one node with ISP 3.2 installed and I cannot setup PHP_FPM from old panel... so i tried to upgrade main... :(

    Waiting for Your kindly reply, Maciej

    I changed version for system PHP i rebooted server and after few minutes got panel working.... OMG. Heart attack...

    double check:
    update-alternatives --config php
    update-alternatives --config php-cgi
    and reboot server.
