short description

I just installed the new v3.2 on a new server (install from scratch) on Ubuntu 20.04.

First everything worked very well, ISPConfig could be opened, I made several settings and then I did some changes in the System/Server Config tabs for several services (mail, web...) and now I only get a 500-error and only the ISPConfig Logo is shown and the logout-admin button. honestly i don't know what setting was the reason, but it seems like something has the wrong datatype in database now...

environment

Server OS: Ubuntu Server OS version: focal 20.04 ISPConfig version: 3.2 - newest from today

log entries

/var/log/apache/error.log

mod_fcgid: stderr: PHP Warning:  Trying to access array offset on value of type null in /usr/local/ispconfig/interface/lib/classes/auth.inc.php on line 61

I already had a look into tpl.inc.php and index.php but I honestly don't have a clue where to continue...

changed the description

I did a fresh install as well on Ubuntu 20.04 and it works fine here. Did you change any settings in php.ini and which exact php version do you use?

Ok, missing information: i use multiple PHP-Versions and followed instructions with sury.org repository to install all versions from 5.6 up to 8.0. and thats really the reason: it was due to running PHP8 instead of PHP7.4 and I found the reason here:

/var/www/php-fcgi-scripts/ispconfig/.php-fcgi-starter

#!/bin/sh
PHPRC=/etc/php/7.4/cgi/
export PHPRC
export PHP_FCGI_MAX_REQUESTS=5000
export PHP_FCGI_CHILDREN=1
exec /usr/bin/php-cgi \
    -d disable_classes= \
    -d disable_functions= \
    -d magic_quotes_gpc=off \
    -d open_basedir= \
    -d session.save_path=/usr/local/ispconfig/interface/temp

the exec line it is using /usr/bin/php-cgi and that was pointing to PHP8 after installing update-alternatives and setting php-cgi to 7.4 it runs again. So maybe this .php-fcgi-starter-script can be improved? maybe

exec /usr/bin/php-cgi7.4 ...

I think this should also be present on systems with only one php-version?

PHP 8 is definitely not supported yet.

So maybe this .php-fcgi-starter-script can be improved? maybe

The starter script is fine, its an issue of the sury repo to replace the default PHP version without asking the admin. Please see the multiserver PHP guide on how to switch back to the correct default PHP version.
