“Several install of Virtualmin”?? I doubt you even CAN install Virtualmin multiple times on the same machine.
Or were you referring to phpMyAdmin? Well, I suppose you can have multiple of those, when installed in separate directories. So you had version 2.11 installed outside of VM and then 3.4.3 installed through VM? What paths did you use for both of them? Or did you use subdomains? Are both in domains under VM control? Is the Apache config correct? What does the “Preview Website” function show?
Yes, my mistake: I speak about multiple phpAdmin installs.
both phpAdmin are in different directories of course.
the VM phpAdmin is installed in a phpadmin subdirectory within a web site domain
When I click on the script installed path, I get to the 2.11 version
the 2.11 is in /usr/share/phpmyadmin, not under VM control
there is a /etc/phpmyadmin/apache.conf that contains the following
Changing the directory name to something else than phpmyadmin made it.
I will also remove this useless, obsolete Debian version of phpmyadmin, but I preferred to make the VM one working before getting rid off the other.
