Enabling OpenSSL in WAMP
I installed the latest WAMP (from wampserver.com) today on my Windows 7 computer.
I have enabled SSL in PHP > PHP Extensions > php_openssl
And Apache > Apache Modules > open_ssl
But when I try to access anything with https:// I get "Problem Loading Page". The apache_error.log says

Answer
The path to php.ini [in case you want that for composer] is C:\wamp\bin\php\php5.4.x\php.ini . This file is not the same as the one that you have if you navigate through the Wamp tray icon
Go there and remove the semicolon as @milesstewart88 says
