EPiServer 7 seems to have some problem with interpret language versions with SSL connection. Symptons are that the "Show All Languages" link is grey (and disabled) and translate page feature is hidden.
SolutionModify the framework.config file siteUrl to use https protocol:
<sites> <site> <siteSettings siteUrl="https://demo.episerver.com/" .../> </site> </sites>I couldn't find any information what should the siteUrl parameter be if site's backend is using HTTPS but frontend HTTP protocol. This is tested with EPiServer CMS 7 (with patch 1). There's also another issue EPiServer 7 with SSL what you should be aware: /2013/02/13/episerver-indexing-service-with-ssl/
