I have a multi server setup with one master and two slaves. The master is running Stretch, fully updated. I upgraded from 3.1.15 to 3.2 and now ISPConfig doesn't work. The upgrade went fine - no errors on all three server but I get an Internal Server error when I go to the panel web site and when I tail the apache2/error.log I see the following: ---- [Fri Oct 23 14:53:20.550802 2020] [core:notice] [pid 15119] AH00094: Command line: '/usr/sbin/apache2' .php-fcgi-starter: line 6: /usr/bin/php-cgi7.0: No such file or directory [Fri Oct 23 14:53:42.051002 2020] [fcgid:warn] [pid 15201] (104)Connection reset by peer: [client xx.xx.xx.xx:59904] mod_fcgid: error reading data from FastCGI server [Fri Oct 23 14:53:42.051057 2020] [core:error] [pid 15201] [client xx.xx.xx.xx:59904] End of script output before headers: index.php ----- The panel had been working immediately before the upgrade. All the web sites and other services that the master hosts are working fine. Thanks in advance.
