Hello, I set up a server (perfect server ubuntu 20.04) I add several php versions : "add-apt-repository ppandrej/php" -> php5.6, 7.0, 7.1, 7.2, 7.3 + 7.4 I modify ispconfig to have several version and it works fine. Yesterday I run apt update, upgrade and now when trying to open myserver:8080/webmail, I have following message : -> Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 7.2.5" I check "update-alternatives --config" for fpm and cgi. Default is 7.4 I switch to composer-2 and update dependencies... Roundcube logs are 10 days old... without anything interesting ! I don't see how to solve ! My thinking is that default version is 7.4. I can't choose php version for Roundcube, so should be default. I don't know where to look for ?
