When trying to set "SSL Cipher Suite" back to default in WHM the default Cipher Suite isn't set back to default.
The Cipher Suite is set based upon the protocols enabled. If the server has a custom "SSL/TLS Protocols" set like the following then those ciphers will be generated instead of the default ciphers.
[14:58:57 server1 root ~]cPs# grep SSLProtocol /etc/apache2/conf/httpd.conf
SSLProtocol all -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
[14:59:03 server1 root ~]cPs#
This can be corrected by accessing WHM and accessing "Apache Configuration »Global Configuration" and setting both "SSL Cipher Suite" and "SSL/TLS Protocols" to default at the same time.
