Hi there! This blog post was published over 18 months ago. A lot can change in that time, so some of the information might now be outdated. It’s worth verifying the details or checking for newer updates.
I was greeted with the following message when i went to update one of my SSL certificates in Virtualmin.
Error - Perl execution failed Undefined subroutine &virtual_server::
get_all_service_ssl_certs called at /usr/libexec/webmin/virtual-server/cert_form.cgi line 95.
This is a nice and easy fix, simply restart webmin from the command line, on CentOS I accomplished this by running:
service webmin restart
