Greetings Running Debian stretch. Wanting to use ispconfig3.1.6 initially. Installing using a recipe called 'The Perfect Server' (https://www.howtoforge.com/tutorial...-stretch-apache-bind-dovecot-ispconfig-3-1/3/) on step 21: error message comes up: No PHP MySQLi functions available. Looked for what I could find using search engine duckduckgo and couldn't find anything to resolve this issue. Unresolvable issue - - - used first dpkg -r then dpkg -P AND apt remove and apt purge to clear my system of ispconfig. Always some error message. Next did an rm -r on /ispconfig. Still it is hanging in there. Tried using the dpkg AND apt removal procedures. Still there. Tried a reboot hoping that something might clear - - - no luck. Downloaded the tar files and unpacked followed by using $ php -q uninstall.php . Still hanging in there. How do I remove this non-functioning software? Does it take a system reinstall to wipe the system of ispconfig?
