Hello, i have installed "Perfect Server Automated ISPConfig 3 Installation on Debian 10 - 11 and Ubuntu 20.04" on Debian 11. Everything was perfect. But after a while i get this error: Unsupported PHP version. Required PHP >= 5.4 and < 8.0. You might need to manually install the phpX.Y package (for X.Y < 8.0) as well as phpX.Y-{cli,intl,json,mbstring}. I turned all Websites from php 8 to 7.4. But Rouncube doesn't work. ISPConfig is using php7.4 Nice Greetings Frank
In the browser mydomain.de/webmail When i see the mailboxes in ISPConfig and klick on the mailbox symbol. And: webserver.mydomain.de:8080/webmail/
Might be that you have installed or updated to mod_php 8? ISPConfig itself uses php-fcgi, so it can be that ISPConfig is working and using PPPHP fcgi 7.4 while Roundcube uses mod_php which was installed as PHP 8.
Thx a lot. I had installed nextcloud and needed some modules. In this session i had aktivated php8.0-fpm but i had forgotten it. I found it in my own documentation After Code: a2disconf php8.0-fpm and Code: systemctl reload apache2 i can use Roundcube again Thank you for that tip. I was not sure if i could disable php8.0 modul. This tip gave me back my memory
Sorry for gravedigging old threads, but this describes exactly my problem. I did too install nextcloud. However the solution provided did not work for me. Code: Conf php8.0-fpm already disabled fixed by using a2disconf php8.1-fpm
