Ok, so you don't have a file named "/usr/local/apache/conf.d/vhosts-ssl.conf".
Your CWP is updated, but trying to access a unused anymore file.
I don't know why you are receiving this message, but surely apache call the SSL files from individual domain files, like "domain.ssl.conf" in directory "/usr/local/apache/conf.d/", called from directive:
IncludeOptional /usr/local/apache/conf.d/vhosts/*.conf
from file:
/usr/local/apache/conf.d/vhosts.conf
... that is called from directive:
Include /usr/local/apache/conf.d/*.conf
from file:
/usr/local/apache/conf/httpd.conf
.. the main apache configuration file.
So, if you have activated some monitoring for apache, that checks the old structure, this program is outdated, and need be updated.
This only can be made by CWP support.
