Help. can't install virtualmin with fetal error

I installed virtual in my vps (centOS 6 64bit), and run a wordpress theme. But when I changed the theme image location on wordpress options. I can’t connect to webmin anymore.
So I uninstall the webmin in linux and try to install again, everything goes fine but at final there comes fatals as follow:

FATAL - Fatal Error Occurred: Installation failed: 0
FATAL - Cannot continue installation.
FATAL - Attempting to remove virtualmin repository configuration, so the installation can be
FATAL - re-attempted after any problems have been resolved.
FATAL - Removing temporary directory and files.
FATAL - If you are unsure of what went wrong, you may wish to review the log
FATAL - in /root/virtualmin-install.log

I’m new on vps and don’t know what’s going on, can anybody help to solve this problem? thanks guys.

There is no way that changing your WP theme could affect how Webmin/Virtualmin works so this two things are completely separate from each other. Second, once you installed any control panel you cant just remove, instead best solution would be to completely wipe out your server and start fresh. Virtualmin like many other control panels is best to install on clean/fresh OS.

Now what happened with your Virtualmin its hard to say not knowing what your log files have to say but i would suggest to re-install your OS and then proceed with Virtualmin. Do not install any additional software before Virtualmin is up and running as this could be another reason why Virtualmin installation failed.

Thanks. Lico. I reinstall webmin again and it’s running well now.
But this is not the first time I can’t connect to webmin.
Maybe this’s something wrong with my operation. Thanks again.
