Hi,

I’m getting a 500 Internal Error when I try to access the Roundcube webmail.
Checking /var/log/roundcube/errors.log, I see the following log entry:

PHP Fatal error:  Uncaught Error: Call to undefined function array_last() in /var/lib/roundcube/program/include/rcmail_output_html.php:319

  • SO: Debian 12.15
  • HestiaCP: 1.10.2
  • Roundcube: 1.7.3

Before the installation everything was working fine. Any clues? Any commands you could give me? Thanks!

Hi,

Show the output of these commands:

grep -r RCMAIL_VERSION /var/lib/roundcube/program/include/iniset.php
ls -lart /var/lib/roundcube
php --version | head -1
apache2ctl -M | grep -Ei  'php|mpm'
3

Very fast…

grep -r RCMAIL_VERSION /var/lib/roundcube/program/include/iniset.php
define('RCMAIL_VERSION', '1.7.3');

ls -lart /var/lib/roundcube

bash: apache2ctl: command not found (I use nginx)

I have also tried rebuilding the domains and restarting the nginx service, as you suggested in other threads. Thanks. I’m still here for you.

Execute this and try again, if you get any error, show the output (don’t copy/paste all the commands at once):

sudo -i
mv /var/lib/roundcube/composer.json /var/lib/roundcube/composer.json.bak
mv /var/lib/roundcube/composer.lock /var/lib/roundcube/composer.lock.bak
mv /var/lib/roundcube/composer.json-dist /var/lib/roundcube/composer.json
source /usr/local/hestia/conf/hestia.conf
COMPOSER_ALLOW_SUPERUSER=1 "/usr/bin/php" "-d disable_functions=" "/home/$ROOT_USER/.composer/composer" --working-dir="/var/lib/roundcube" update --no-dev --no-interaction --optimize-autoloader

No errors were encountered. It seems to be working correctly. Should I be concerned about future updates? Could a file be deleted or overwritten, causing the same error to appear? Thanks as always, Sahsanu.

I’m glad it fixed the issue.

The problem here is that Roundcube doesn’t overwrite composer.json. Instead, it adds the new version as composer.json-dist, so composer.json is never updated.

The complication is that we could overwrite composer.json to avoid these kinds of problems, but doing so could break the installation of someone who has modified composer.json because they’re using a plugin that requires those changes.
