When accessing the Global Configuration interface located in "Apache Configuration", under WHM. An error will be presented if you enter you an insecure SSL/TLS Protocol setup such as the following:
ALL -SSLv2 -SSLv3
In cPanel v90.0.5, insecure SSL/TLS Protocols can no longer be enabled for cpsrvd, cpdavd, and Apache through the WHM interface (CPANEL-33628).
Doing so will result in the below error message:
The following settings are invalid and were rejected:

These protocols are insecure we do not advise enabling them, but if you wish to proceed you can still override the setting by making use of Custom Apache Templates.
