With following versions installed:
OS X 10.11.4 Beta (15E27e)
AH00526: Syntax error on line 581 of /Library/Server/Web/Config/apache2/httpd_server_app.conf: server.app "SSLProtocol: Illegal protocol 'TLSv1.2'"
The website, wiki and so on suddenly don't work. And I upgraded Server.app to 5.0.19(15s5065c). Not working. I deleted all files related to Server.app (including /Library/Server/) and reinstalled it. Not working.
How to fit it? Does the openssl version in Server.app cause it? I installed the openssl/1.1.0-pre2, but I don't know how to make it work with Server.app (openssl/1.1.0 is already working on my Mac).
