Roundcube in ispmanager 6.107 and above
Starting with version 6.107, ispmanager comes with its own Roundcube build based on the stable version of the web-client. This will allow supporting new features and developing Roundcube plugins. The new Roundcube will be available on all currently supported operating systems.
After ispmanager upgrades to 6.107 or above, Roundcube will be forced to update.
Instead of native PHP versions, Roundcube will now use the alternative PHP 7.4:
- Nginx and Apache will use the PHP-FPM mode. To support FPM, the proxy and proxy_fcgi modules will be installed for Apache. The configuration file:
/opt/php74/etc/php-fpm.d/roundcube.php-fpm.conf.
- OpenLiteSpeed will use the LSAPI mode. The configuration file:
/usr/local/lsws/conf/php/isp-php74-roundcube.conf
.
