I just installed virtualmin via install.sh on a new dedicated server with CentOS 6.x.
I have found this topic https://www.virtualmin.com/node/19000 and I followed the instructions up to the 4th message https://www.virtualmin.com/node/19000#comment-85230 but I still get the error.
I am not a pro, this is my 3 dedicated server but the first one that comes clean of any Plesk, etc. I may need detailed instructions on how to proceed.
thank you for helping
