Hi, Over the weekend we performed a system upgrade from Debian 9 to Debian 10 Buster and upgraded all the modules as well. While 90% is working such as the ISPConfig 3 panel (which was previously updated to 3.1.14) the problem is with some sub-sites that were running perfectly previously. Initially, we saw errors in regards to the APCu module not running for cache (had ensured that it had been installed), then after it was stating that it was missing other modules, which we knew and verified as being installed for PHP. After a phpinfo() on the vhost site we see that it was still running on php7.0, whereas the default for ISPConfig after another phpinfo() was 7.3. Thus for those older sites remained at pointing at the old PHP7.0-fpm vs the system's default of PHP7.3-fpm. We verified this by looking at the /etc/apache2/conf/sites-enabled/<site> and found that it was pointing still at old /var/lib/php7.0-fpm URLs not the new php7.3-fpm. Thus as a test, we created a new site with php-fpm enabled and it was still pointing to the old php7.0-fpm URLs. After digging around a bit, I have not been able to see where ISPconfig would set the updates to the FPM. I don't care about having multiple php versions allowed and only want it to use the latest 7.3 version. Thus is there a location where one can update and correct this? Please let me know as it is frustrating that it isn't updating properly.
