@hklcf You are welcome. Push the Thanks button if it worked for you.
However, I still would like to have my 2 questions answered. As it currently stands, anyone who follows The Perfect Server - CentOS 6.4 x86_64 (Apache2, Dovecot, ISPConfig 3) and ISPConfig 188.8.131.52, will have a non-working server. I would like the whole world to enjoy ISPConfig. Thank you to the authors for putting so much time and effort into this project.
1) Will the author fix The Perfect Server - CentOS 6.4 x86_64 (Apache2, Dovecot, ISPConfig 3) installation guide, so that everyone can enjoy this software?
2) What is the correct way to make everything work correctly? My solution was meant to be temporary until the author can tell us the correct way to fix the problems that occur.
