Hello Friends, After I have upgraded from Ubuntu 20.04 to Ubuntu 22.04, spellcheck of of Roundcube does not work any more. It is because the default spellcheck engine requires extra php packages. $config['spellcheck_engine'] = 'enchant'; Install your php version modules, for example, sudo apt install php7.4-enchant php8.0-enchant php8.1-enchant php8.2-enchant php8.3-enchant
