#1. I created a new Ubuntu 18.04 server and installed ISPConfig using the Install-Script at: https://www.howtoforge.com/tutorial/ubuntu-ispconfig-automated-install-script/. I did NOT install the Xcache as I Googled and found Opcache is built into PHP 7.x and is superior to Xcache. But, I am not sure if Opcache is enabled by the Install-Script. How can I know if Opcache is enabled? Which PHP .ini file do I check? #2. What's the best setup for PHP 7.x for ISPconfig & Wordpress? #3. The Install-Script asked me for a password for phpMyAdmin but did not ask for a UserName. What UserName do I use when logging into phpMyAdmin? Thanks.
