How to fix 'suexec command was not found on your system.' in Virtualmin
I ran into this error message in Virtualmin when I want to disable Bind and Mail for Domain, I searched around for answers and I couldn't find it. Finally I found out that Suexec was not installed correctly, so I reinstalled again with the command
apt-get install apache2-suexec-custom
And then it changed to another error message, where it shows.
