I am still using Virtualmin 3.93 PRO so I am not sure if this is fixed in 3.94.
In the Virtual Server -> Manage Server -> Manage SSL Certificate -> New Certificate tab, the manual text entry for a new Certificate does not seem to like tagging on the Intermediate CA.
The error I am getting is :
Failed to install certificate : Missing or invalid signed SSL certificate : Line 30 does not look like PEM format
The current solution I found was to place both the certificate and the intermediate into a .pem file and upload it.
Hope you guys have a great day,
